CVE-2020-11981
When using CeleryExecutor, if an attacker can connect to the broker (Redis, RabbitMQ) directly, it is possible to inject commands, resulting in the celery worker running arbitrary commands.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 36.8%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
