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.\n\n## Affected packages\n\n- `bbot >= 2.0.0, <= 2.8.4`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `bbot 2.8.5`","depth":"sunlit","depthScore":17,"depthScoreParts":{"impact":17.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
