[Bug 42373] New: Add ability to disallow unbounded patron api searches
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42373 Bug ID: 42373 Summary: Add ability to disallow unbounded patron api searches Initiative type: --- Sponsorship --- status: Product: Koha Version: Main Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: REST API Assignee: koha-bugs@lists.koha-community.org Reporter: kyle@bywatersolutions.com QA Contact: testopia@bugs.koha-community.org CC: tomascohen@gmail.com In a Koha instance with multiple hundreds of thousands of patrons, a patron api search with _per_page=-1 can cause a single worker to query the database for all patrons, then query the database multiple times for each of those patrons to decorate the resulting patrons ( fees owed, etc ). If the _per_page size is greater than the limit we specify, Koha should refuse the request and emit an http status code 400, with a clear error body explaining the max allowed _per_page value. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42373 --- Comment #1 from Kyle M Hall (khall) <kyle@bywatersolutions.com> --- Created attachment 197512 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=197512&action=edit Bug 42373: Enforce RESTMaxPatronsPageSize in patron list endpoint In a Koha instance with hundreds of thousands of patrons, an API request to /api/v1/patrons with _per_page=-1 can cause a single worker to query the database for all patrons, then make multiple additional queries per patron for decoration (fees owed, etc), effectively locking up that worker. This patch adds a new system preference RESTMaxPatronsPageSize. When set to a positive integer, requests to the /patrons list endpoint with _per_page=-1 or _per_page greater than the configured limit will be refused with HTTP 400 and error_code 'max_page_size_exceeded'. When left empty or set to 0, the existing behavior is preserved. Test Plan: 1) Apply this patch 2) Run updatedatabase.pl 3) Go to Administration > System preferences > Web services > REST API 4) Note the new RESTMaxPatronsPageSize preference 5) Leave RESTMaxPatronsPageSize empty 6) Make an API request: GET /api/v1/patrons?_per_page=-1 7) Note the request succeeds as before! 8) Set RESTMaxPatronsPageSize to 100 9) Make an API request: GET /api/v1/patrons?_per_page=-1 10) Note the request is rejected with a 400 and a clear error message! 11) Make an API request: GET /api/v1/patrons?_per_page=500 12) Note the request is rejected with a 400! 13) Make an API request: GET /api/v1/patrons?_per_page=50 14) Note the request succeeds! 15) Make an API request: GET /api/v1/patrons?_per_page=100 16) Note the request succeeds!

We should offer a flexible way to address the "max page size" need for the REST API. We could have a single RESTMaxPageSize pref (applied to all endpoints), or consider a JSON pref {patrons: 100, biblios: 50}. It will also helps to adjust the menuLength in a generic way (in datatables.js). -- You are receiving this mail because: You are watching all bug changes.
