Summary

SpiceDB WriteRelationships fails silently if payload is too big

Details

Impact

Users who 1. use the exclusion operator somewhere in their authorization schema 1. have configured their SpiceDB server such that --write-relationships-max-updates-per-call is bigger than 6500 1. 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 their WriteRelationships call, when in reality that call failed,
receive incorrect permission check results, if those relationships had to be read to resolve the relation involving the exclusion

Patches

Upgrade to v.145.2.

Workarounds

Set --write-relationships-max-updates-per-call to 1000.

CVE-2025-64529 (GCVE-0-2025-64529)

Vulnerability from cvelistv5 – Published: 2025-11-10 22:28 – Updated: 2025-11-12 20:12

Title

SpiceDB's WriteRelationships fails silently if payload is too big

Summary

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-call` is 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 their `WriteRelationships` call, 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-call` to `1000`.
