- Summary
- SpiceDB's WriteRelationships fails silently if payload is too big
- Details
-
SpiceDB is an open source database system for creating and managing security-critical application permissions. In versions prior to 1.45.2, users who use the exclusion operator somewhere in their authorization schema; have configured their SpiceDB server such that
--write-relationships-max-updates-per-callis bigger than 6500; and issue calls to WriteRelationships with a large enough number of updates that cause the payload to be bigger than what their datastore allows; will receive a successful response from theirWriteRelationshipscall, when in reality that call failed, and receive incorrect permission check results, if those relationships had to be read to resolve the relation involving the exclusion. Version 1.45.2 contains a patch for the issue. As a workaround, set--write-relationships-max-updates-per-callto1000. - Database specific
