Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
BBOT versions 2.0.0 up to but not including 2.8.5 are affected. The docker_pull module uses the realm value from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validating it. An attacker in a man-in-the-middle position between BBOT and a Docker registry could redirect authentication requests to an arbitrary endpoint, potentially leaking tokens. Upgrade to BBOT 2.8.5.
