Affected packages

• PyPI bbot: >= 2.0.0, < 2.8.5 → fixed in 2.8.5

Description

The `docker_pull` module uses the `realm` parameter from a Docker registry's `WWW-Authenticate` response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication request to an arbitrary endpoint, potentially leaking authentication tokens.
