Frameworks in other languages use bound parameters natively because it is inherently more secure than doing the escaping in the framework and passing pure strings to the mysql server to process. replacements are escaped and inserted into the query by sequelize before the query is sent to the database. For executing a single query, it'll do three executions (Prepare, Run the query and close). bind parameters can be used without explicit prepare. By clicking Sign up for GitHub, you agree to our terms of service and the effort needed to implement this for postgres, sqlite, mysql and mssql I appreciate this isn't directly helping move this bug forward, but it may help someone else struggling with why the persistance of 'BLOB' types in MSSQL under Sequelize is so slow! I was naturally very concerned and end up here. @janmeier , I think this is an oversimplification. With prepared statements there will be some chances that query might be reused. These templates are best known as "Prepared Statements", or sometimes "Parameterized Statements". Then a better implementation is to use PREPARE. job at improving the API, functionality and stability of this project. How to check whether a string contains a substring in JavaScript? How to create a Sequelize model instance, without saving it in the database? Edit: Would love to see some resources on prepared statement performance actually. With v5 all INSERT / UPDATE statements are using bind parameters. Sequelize a one-to-many relationship. idiot for not obviously accepting that fact). It came down to the revelation that Oracle could only run a certain number of query plans simultaneously before they would queue. The Postgres driver ( @mickhansen sorry I didn't look This is awesome, it will work already with values and you can specify bind as a boolean instead of changing the syntax. @taoeffect node-sql is just a query builder, not a driver. Do I get any security benefits by natting a a network that's already behind a firewall? Maximum call stack size exceeded in react-admin with ra_data_graphql_simple when schema with nested object, Sequelize adding many-to-many relation with additional data not working, Error with an insert in nodejs and Postgres using sequelize. Typically you only want the SQL query. Escaping would then happen when processing bind params. I am starting to migrate sequelize to node-mysql2 as our first step. Is there any defacto standard on this though? Instead of saving the whole query with placeholders, I save an array of string parts (which is what is given to a tagged template string. The query is planned before the parameters are inserted, and thus does not allow you to inject SQL, https://github.com/brianc/node-postgres/wiki/Prepared-Statements#parameterized-queries. You can learn more about sequelize.query() method here. All query generator methods need to be refactored to return `{query/sql: '', replacements: ''}, and we need ways of merging this recursively. But the risk that applications process JSON data and thus run SQL queries that where never intended still remains. I prefer your API designs over the other guys', but I personally can't peddle something while I know it's not architected for safety. Create JOIN queries through Sequelize association Future Studio is helping 5,000+ users daily to solve Android and Node.js problems with 460+ written few open source projects and you are one of the best when it comes to Bind parameters are referred to by either $1, $2, . I can certainly sympathize with anyone that wants a change in an OSS library, it's not very often they put in any work for to help accomplish it though :). Preparing the statement of course costs a bit time but the following executions will be faster because the SQL does not need to be parsed anymore. But we've not forgotten it and are still thinking about how best to refactor. management is far from easy. How to create prepared statements in Sequelize? The sequelizepackage we used above supports them as well, and so we could fix the vulnerability by modifying our function to look like this: function findItems(req, resp) { try { // Find the relevant items Sequelize CLI how to create migrations from models? You are working far too hard trying to emulate that behavior, and I'm curious to know how many of the library dependencies are only there for that purpose. Never Mind, The sequelize.query has an option called replacements that is escaped automatically.. replacements are escaped and inserted into the query by sequelize before the query is sent to the database. Definitely no CLS, params and sql should be passed around explicitely, i'll likely make a stab at this soon. don't think you should defocus solely because of the security argument. (1) in the same transaction/session/connection it can be reused and (2) the I believe we already have a solution in place for cross dialect replacements. @holm I appreciate your feedback. Sign in If you need more details about the query composition, you may look through the query object as well. Be aware when using .query (), you do not perform an actual prepared statement. How can execute multiple statements in one query with Rails? My sequelize layer is hidden behind a graphql layer, so I have already one library which is doing type safety and input control on my inputs. When an EXECUTE command is subsequently issued, the prepared statement is planned and executed. How to create assocations in Sequelize migrations? To be honest I am extremely surprissed that bind/prepared statements is not used for a modern SQL framework. sequelize.query('SELECT * FROM users WHERE name LIKE :search_name ', { replacements: { search_name: 'ben%' }, type: sequelize.QueryTypes.SELECT } ).then(projects => { console.log(projects) }) Is anyone else bothered by the fact that using a single '$' as a bind parameter delimiter causes great potential for false positives? Does English have an equivalent to the Aramaic idiom "ashes on my head"? The sequelize.query() method is a function that allows you to write and run a raw SQL query. As this post shows, ORM packages such as Sequelize and MySQL can and do have flaws that can leave you exposed. We can implement it but main issue I think is performance. In that case yes, users can definitely be "fooled" to create malicious queries, but sequelize doesn't really have control over that - We can only help them by recommending bind parameters. If JWT tokens are stateless how does the auth server know a token is revoked? Okay it doesn't work with replacements, but what about values? I also noticed that it looks like Sequelize has migrated to MySQL2 which supports bound parameters but according to the documentation for the latest release of v3, MySQL prepared statements are still not supported. Frameworks in other languages use bound parameters natively because it is inherently more secure than doing the escaping in the framework and passing . Future Studio Obviously it should be tested. This is kind of a big deal, as in "One of the classic blunders" big deal, and I can completely sympathize with @bill-myers for his brash "fix this yesterday". // will use `values` and sequelize's built-in replacement, 'Both `replacements` and `bind` cannot be set at the same time'. Again, you are doing great work with sequelize. A prepared statement is a server-side object that can be used to optimize performance. 600VDC measurement with Arduino (voltage divider). How to use Sequelize create with nested objects and relations. These are perfectly fine to use with transaction pooling. According to #998, the issue of prepared statements and parameter binding through the native mysql driver was considered and rejected previously.. Well, for a first implementation in PG we could just use parameterized queries without PREPARE, which is more secure and has the same performance as a normal query. Connect and share knowledge within a single location that is structured and easy to search. Have a question about this project? But there's a big difference between people complaining about missing features and someone opening a ticket about a fundamental security issue in a widely deployed library. Prior MySQL version 4.1, a query is sent to the MySQL server in the textual format. Creator of Futureflix and the learn hapi learning path. What to throw money at when trying to level up your biking from an older, generic bicycle? As @janmeier stated a while back, PSs in and of themselves don't do anything for security. Though general escaping would reduce such possibilities to near zero. According to https://github.com/sequelize/sequelize/issues/998, the issue of prepared statements and parameter binding through the native mysql driver was considered and rejected previously. Right now, I've wrapped my queries in a function that doubles all '$' when followed by a regex word character before passing to sequalize.query. @janmeier, the structural alteration of the query happens before sequelize is called, in application code. @sushantdhiman any update on the SELECT statements and prepared statements ? same prepared statement can be used by multiple connections. @mdarveau @janmeier in mysql statements are scoped by connection and can't be reused between connections ( and destroyed server side when client connection is closed / dies ) That's why my initial api was focusing on automatic creation/caching of statements. . Just to make sure I understand, when using raw queries with bind, the native driver bind / parameterization capabilities _do_ get utilized, correct? I'm not entirely sure how you could even determine when that type of request is "malicious", to be honest. Thats something we can't control. A way of specifying attr = condition. I would like to reopen the issue as a security concern for queries being run against the server. Handling unprepared students as a Teaching Assistant, Rebuild of DB fails, yet size of the DB has doubled. highly negative and doesn't really seem to take into account the resources Read the next paragraph for more details! This ticket is 20, 21 months old? @felixfbecker sequelize.query already supports an object, look at the source code i've linked three seperate times now :). Passing a bind parameter, leaves all the work on the server only. It does support I have since done a penetration test on my application, and while the lack of parameterized queries is a flag raised in said testing, all sql injection attempts fail. Prepared statements are using the so called binary protocol. $? which prepared statenents wouldn't have done much again. So for a running Node app the overall performance will be faster after the first queries. Is the inverted v, a stressed form of schwa and only occurring in stressed syllables? When the PREPARE statement is executed, the specified statement is parsed, analyzed, and rewritten. The include part could be a roadmap item. Reply to this email directly or view it on GitHub Would it help if someone opened another ticket titled 'Bind Parameters for Security'? As for performance I doubt there is much to gain. Imagine that for each query, the prepared statement need to be sent and There is no visibility that how much memory is consumed by a prepared statement. Through the API gateway, I have no injection exposure. Picking them out of the raw statement would likely be too error prone and they're already escaped at that point. This means no risk of any incompatibility. Is this the real root cause? guarantee security. I also believe that prepared statements can improved performance _if used For queries generated by sequelize on the other hand, we do control the queries, and can use parameterized queries properly - We don't do at the moment, but the infrastructure is there. If you need more details about the query composition, you may look through the query object as well. It will be closed if no further activity occurs. It's also common to have '$' appear in mssql system column names (such as __$start_lsn used in change data capture) so using simply '$' as a delimiter was not a good decision IMO. Stack Overflow for Teams is moving to its own domain! pg abstracts around this by simply providing a name option to the query method, and the the query will be prepared once and then reused. That's right, but remember sequelize is an ORM and not a DB driver. Which method is use to create prepare statements? The query generator should also be deterministic, e.g if you pass the same options it should result in the same query, even if you change the key order in the where clause it should result in the same WHERE condition. But we still need to firgure out how to pass values and query around. On 9 April 2015 at 01:26, Mick Hansen [emailprotected] wrote: @efuquen https://github.com/efuquen I understand your sentiment. I've been following this discussion on the sideline, but I feel I should give my input as well. Seems .query() function has supported parameterized query, But the Model operations not. @mickhansen I was only trying to say that prepared statements without bound parameters don't scale very high. It does prepared statements by default (doesn't let you not do them) and seems to support all those databases. I believe I was misdiagnosed with ADHD when I was a small child. I used the following code. just to say, I would much like to see bind param to be used. There may be some benefit from Postgres but they're a bit vague on the details. I consider something that would improve security greatly and make the web a safer place of critical importance, so if other features are being prioritized over this it really bums me out. 2022 for mysql, and $N for postgres in the final steps. 4. Get your weekly push notification about new and trending Hopefully SELECT will be converted to use bind internally as well, https://github.com/sequelize/sequelize/blob/master/docs/upgrade-to-v5.md#others. In turn, MySQL returns the data to the client using textual protocol. I just wanted to pop in here and weigh in since I've been using this library for the last 2 days and this immediately got my attention the moment I noticed in console that full query strings were being emitted. documentation or benchmarks on that (other than that i'm apparently an Developer. Or is it possible to pick these parameters out of raw statement before executing ? Share answered Apr 18, 2021 at 2:35 Robinson De La Cruz 126 6 Add a comment javascript typescript sequelize.js This works for me, since I invented my own binding syntax @ which I subsequently replace with $param. That is, if the thing that you were intending to do has changed so much after the parameters have been passed in, the third party must have passed in something that changed what you have intended. Googling around it looks like perhaps Oracle still works this way. I've a confirmed use-case where the design decision not to use prepared statements/parameterised queries does have a dramatic affect on performance, which I'm documenting here so that someone else doesn't have to re-research this behaviour! Ideally, this is where parameters would be sent instead of part of the query. I follow and use quite a At least for postgresql (and node-pg) there is a difference between "prepared statement" and "using bind parameter". As for a cross-dialect syntax, does the SQL standard define this syntax? Copyright 2022 www.appsloveworld.com. Except replacements are escaped and inserted into the query by sequelize before the query is sent to the database, while bind parameters are sent to the database outside the SQL query text. Adding associations to sequelizejs models. @jdmarshall Increased security would be the goal, and we're generally pretty quick about fixing security issues. If you look at how complex the prepared statement caching options are If however I re-write the sql used in my test app to be of the following form: INSERT INTO [Artifacts] ([art_id],[content]) VALUES (N'080abd3c-0dc4-469b-8c55-33532a4891e6',@data), and provide the tedious request with the 'data' parameter containing my Buffer, the result is instantaneous (or near enough! By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Sequelize passes two arguments to your custom logging function: the generated sql statement and a JavaScript queryObject. don't be affected too much by negative comments. @sushantdhiman Prepared statements might have a minor performance impact if your pools are not saturated, however if that's the case you probably don't care about the few ms difference. This is helpful during development, but also noisy because your terminal is flooded with SQL statements. @mickhansen With sql-template-strings I solved this by having a SQLStatement class that has getters for each of the dialects, so only the one that is needed is computed, and then the index for $ is computed inside the getter: https://github.com/felixfbecker/node-sql-template-strings/blob/master/index.js#L15. I've tagged this issue as a feature request, and others will be able to flag their support. It's frustrating for us old guys to watch every crop of languages over multiple decades repeat the same security mistakes. This double the The link you provided seems to cover general SQL injection protection - I was hoping for resources digging into framework vs database. @mbroadst Does the MSSQL driver support prepared statements? I get this is an open source project and if I really needed this I could submit a PR myself (which I don't, since I'm not using sequelize). How do I return the response from an asynchronous call? Ah sorry I just saw in the docs that bind is an object, not a boolean, @felixfbecker values maps to replacements atm, but that could be changed (but in that case we might just want to change to native binding for all dialects).
