{"id":"CVE-2025-64529","state":"PUBLISHED","title":"SpiceDB's WriteRelationships fails silently if payload is too big","description":"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`.","publishedAt":"2025-11-10T22:28:51.589Z","updatedAt":"2025-11-12T20:12:52.552Z","severity":{"score":2.7,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U","source":"GitHub_M"},"assigner":"GitHub_M","products":["authzed spicedb"],"affected":[{"vendor":"authzed","product":"spicedb","versions":[{"version":"< 1.45.2","status":"affected"}]}],"references":["https://github.com/authzed/spicedb/security/advisories/GHSA-pm3x-jrhh-qcr7"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/64xxx/CVE-2025-64529.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-64529","state":"PUBLISHED","datePublished":"2025-11-10T22:28:51.589Z","dateUpdated":"2025-11-12T20:12:52.552Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-11-05T21:15:39.401Z"},"containers":{"cna":{"title":"SpiceDB's WriteRelationships fails silently if payload is too big","descriptions":[{"lang":"en","value":"SpiceDB is an open source database system for creating and managing security-critical application permissions.
