All versions of Flower, a web UI for the Celery Python RPC framework, as of 05-02-2022 are vulnerable to an OAuth authentication bypass. An attacker could then access the Flower API to discover and invoke arbitrary Celery RPC calls or deny service by shutting down Celery task nodes. A fix was released in version 1.2.0.

DISPUTED Flower 0.9.3 has XSS via the name parameter in an @app.task call. NOTE: The project author stated that he doesn't think this is a valid vulnerability. Worker name and task name aren’t user facing configuration options. They are internal backend config options and person having rights to change them already has full access.
