I propose that each whereItemQuery items returns something like {query: 'col = $? idiot for not obviously accepting that fact). Creator of Futureflix and the learn hapi learning path. What are you doing? With v5 all INSERT / UPDATE statements are using bind parameters. That said, I do hope that the security benefit of a second lock on the database door (prepared/parameterized statements) is realized soon by this library. Do you have any suggestion how to capture all the parameters passed to methods, should we use cls like system OR may be maintain a parameters field in options which will be passed down to query? The MySQL 2 driver supports 1 but not 2 ( added to Sequelize at some point, but you guys are doing an incredibly good To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

I look forward to the conversion being complete. Thats quite rock solid. in fairness they might not be running penetration tests on their codebase). So the sql client doing the quoting must be in perfect sync with the server. If an end-user decides that they want to map a request body directly to a where statement without any sort of validation / permissions / ACL scoping, then they should probably be ready to accept a request body directly to their where statement. The generated sql query may look like this: Notice the Executing (default): prefix in the generated SQL statement. We use node-mysql though, plus we have support for sqlite and postgres aswell. As for a cross-dialect syntax, does the SQL standard define this syntax? (also say switching to node-mysql2 rather than node-mysql might take a performance hit). As @janmeier stated a while back, PSs in and of themselves don't do anything for security. vulnerability in sequelize has been from an injection into the column name, prepared statements? How does pooling plays with prepared statements. replacements are escaped and inserted into the query by sequelize before the query is sent to the database sequelize.query ('SELECT * FROM users WHERE name LIKE :search_name ', { replacements: { search_name: 'ben%' }, type: sequelize.QueryTypes.SELECT } ).then (projects => { console.log (projects) }) Share Follow answered Mar 12, 2018 at 19:27 We appreciate that the issue has been brought up, but we have lots of other things to tend to - We are looking into it, but we are not going to fix it yesterday. @jdmarshall Increased security would be the goal, and we're generally pretty quick about fixing security issues. You signed in with another tab or window. What to throw money at when trying to level up your biking from an older, generic bicycle? Developer. The justifications are in the original issue i believe, one of them being that the drivers didn't support it - Not sure if that is the case anymore? 4. First is it possible, I think it should be as they're safer than raw queries and prevent sql injection. This could lead to memory issues down the road. you quantify the exact security benefits? It would usually have parameters, but that is not a must. Once its done we can think about an API to keep all the values for prepared statements. So, you are emulating a prepared statement.

Yes, but using values as a property is great. @mickhansen sure does! Pg explicitly states that prepared statements are per connection http://www.postgresql.org/docs/9.4/static/sql-prepare.html and I'm pretty sure mysql and mssql are the same. how to create correctly?

But you almost certainly shouldn't be doing this ;), Very surprised there's no parameter support for mysql. on my list: #3495 https://github.com/sequelize/sequelize/issues/3495 I can't see how any DBMS would implemented prepared statements that support @mdarveau's 2nd point. I appreciate this project and the fact that it is open source, but leaving security to the developers when it can be handled at the framework level, is not going to be a sound strategy. It will be the same for the same query. Which method is use to create prepare statements? @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. 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 :). Prior MySQL version 4.1, a query is sent to the MySQL server in the textual format. A way of specifying attr = condition. @felixfbecker We already support that type of literal in query so yeah that could be a goal. Never Mind, The sequelize.query has an option called replacements that is escaped automatically. node-mysql2 rather than node-mysql might take a performance hit). Have you folks considered using node-sql to do this? Also sequelize.query() would need to support a query object as argument. which prepared statenents wouldn't have done much again. transaction/connection but you would get the a performance hit for all The security benefits are well documented, personally I would think that would trump most if not all other issues outside of bugs breaking basic functionality. Do I get any security benefits by natting a a network that's already behind a firewall? The include part could be a roadmap item. (numeric) or $key (alpha-numeric). There's also no garantee that a separate query builder supports everything we need. Definitely no CLS, params and sql should be passed around explicitely, i'll likely make a stab at this soon. Unexpected data in req.body is probably not something we can actually code against, but we can still advice our users to be careful. At least for postgresql (and node-pg) there is a difference between "prepared statement" and "using bind parameter". 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.

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! life cycle of the session. Please These are perfectly fine to use with transaction pooling. number of round-trips to the DBMS for each query. I know that it is no small matter to rebuild an entire query language system (having done so once myself in another language) so I accept that this isn't a fix yesterday thing, but I wanted to express that I still think it's a priority. Passing a bind parameter, leaves all the work on the server only. The link you provided seems to cover general SQL injection protection - I was hoping for resources digging into framework vs database. And plus, it was viewed that it's never possible to cover the myriad of possibilities to inject given all possible permutations of sql constructs. Ideally, this is where parameters would be sent instead of part of the query. . To learn more, see our tips on writing great answers. I see the theoretical security benefit, but not much other than that. execute the same query (excluding parameters) multiple times in the same This is helpful during development, but also noisy because your terminal is flooded with SQL statements.

In queries will become a problem since they need to formatted differently that other types of arrays. Is anyone else bothered by the fact that using a single '$' as a bind parameter delimiter causes great potential for false positives? But the risk that applications process JSON data and thus run SQL queries that where never intended still remains. @efuquen https://github.com/efuquen Your comment was appreciated while If we don't care about meaningful query names, we could just use a hashing function to hash the SQL string.

But it's worth investigating, Sqlite and postgres already has support for bind parameters in raw queries, thanks to @User4martin (https://github.com/sequelize/sequelize/pull/4688) - So all it takes for this to be fixed is for someone to begin converting the query generator to return { sql, bind }. You can omit the name but then the SQL will be parsed each time and you get no performance benefit. 2022 But is this really about prepared statements, like sending a. I see https://github.com/yang/rel not sure on its quality, doesn't seem very active. Maybe start out with INSERT's, might be the simplest. 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). for mysql, and $N for postgres in the final steps. Yes, we need some data store which will keep the values while replacing the ? A prepared statement is a server-side object that can be used to optimize performance. just to say, I would much like to see bind param to be used. (also non-attack spells). I don't doubt that security would improve from a theoretical point of view, however from a practical point the effects are probably minimal. Read the next paragraph for more details! @jdmarshall The performance improvements of reusing a query plan assumes you are constantly reusing the same connection (which is not necessarily the case with pooling). 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. 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. @mickhansen pg and sqlite3 both have support for prepared statements.
