CVE-2026-40091

Credential disclosure via unredacted datastore URI logging

Published Apr 14, 2026 · Updated Apr 15, 2026

Sensitive-data exposure in AuthZed SpiceDB 1.49.0 through 1.51.0 allows local users to read datastore credentials from startup logs. At info level, the startup configuration logger serializes DatastoreConfig.URI in full instead of redacting the password embedded in the datastore DSN. Exposure requires access to SpiceDB startup logs and an info-level launch; it discloses the datastore password without altering data or service availability.
