CVE-2026-92782

Chroma through 1.5.9 fails to validate tenant and database segments when resolving collections, allowing authenticated attackers to access collections from other tenants by knowing the collection identifier. Attackers can read, modify, and update records in foreign collections by issuing requests under their own tenant path, bypassing authorization checks.
