CVE-2026-126539 PUBLISHED

Directus before 12.1.0 Authorization Bypass via Public WebSocket REST Interface

Assigner: VulnCheck
Reserved: 11.11.2026 Published: 11.11.2026 Updated: 11.11.2026

Directus before 12.1.0 contains an authorization bypass vulnerability that allows unauthenticated attackers to skip permission checks by sending a failed auth message on public-mode WebSocket connections. Attackers can send an invalid token so handleAuthRequest sets accountability to null, then read, create, update or delete records in any user-defined collection.
