CVE-2025-49011

Name of the Vulnerable Software and Affected Versions SpiceDB versions prior to 1.44.2

Description The issue affects SpiceDB, an open source database for storing and querying fine-grained authorization data. On schemas involving arrows with caveats on the arrow'ed relation, when the path to resolve a CheckPermission request involves the evaluation of multiple caveated branches, requests may return a negative response when a positive response is expected.

Recommendations For versions prior to 1.44.2, update to version 1.44.2 to resolve the issue. As a temporary workaround, do not use caveats in the schema over an arrow'ed relation.
