CVE-2026-44847 (GCVE-0-2026-44847)

Vulnerability from cvelistv5 – Published: 2026-05-26 20:16 – Updated: 2026-06-01 17:09

Title

MaxKB: Webhook Trigger Authentication Bypass

Summary

MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.

Severity

7.5 (High)
