These address the reported authentication bypass and shell-injection path in source. PR #6207 (9c6331991c5e6e43d755bd59c151864ef28fdc11) also removes the four version-control policy overrides used by the zero-role chain. No fixed released package or container image has been established; PyPI 0.9.80 predates these merges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
