Vulnerability details
Directus is a real-time API and App dashboard for managing SQL database content. Starting in version 9.12.0 and prior to version 11.9.0, Directus Flows with a manual trigger are not validating whether the user triggering the Flow has permissions to…

the items provided as payload to the Flow. Depending on what the Flow is set up to do this can lead to the Flow executing potential tasks on the attacker's behalf without authenticating. Bad actors could execute the manual trigger Flows without authentication, or access rights to the said collection(s) or item(s). Users with manual trigger Flows configured are impacted as these endpoints do not currently validate if the user has read access to `directus_flows` or to the relevant collection/items. The manual trigger Flows should have tighter security requirements as compared to webhook Flows where users are expected to perform do their own checks. Version 11.9.0 fixes the issue. As a workaround, implement permission checks for read access to Flows and read access to relevant collection/items.

Why these techniques?
The vulnerability in Directus allows unauthenticated remote attackers (PR:N) to trigger manual Flows without permission validation on payloads, enabling exploitation of the public-facing web application/API for unauthorized execution of potentially privileged workflow tasks.

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.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
