Overview
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the absence of CSRF protection on state-changing endpoints when OAuth cookie-based authentication is in use. An attacker can trick an authenticated user into visiting a malicious page that issues forged requests to the Flower API, allowing unauthorized state-changing operations (e.g. task revocation or worker control) and potentially crashing workers.
Note: This is only exploitable when OAuth cookie-based authentication is enabled.
