Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Session content review can reveal authentication bypasses or failures in session establishment.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
Documented IA policy and procedures require proper authentication mechanisms to be defined and followed, reducing improper authentication.
Requires adaptive authentication under specific conditions, directly strengthening authentication mechanisms against improper or insufficient authentication.
Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
Requires unique identification and authentication of organizational users, directly preventing improper authentication.
Enforces unique device identification and authentication before any connection is established, directly mitigating improper authentication weaknesses.
Directly requires implementation of compliant authentication mechanisms to cryptographic modules, preventing improper authentication.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unauthenticated access to public webhook endpoint due to broken auth class enables remote exploitation of the application (T1190).
NVD Description
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.
