GHSA-PQHF-P39G-3X64 uv allows ZIP payload obfuscation through parsing differentials

Impact In versions 0.9.5 and earlier of uv, ZIP archives were handled in a manner that enabled two parsing differentials against other components of the Python packaging ecosystem: 1. Central directory entries in a ZIP archive can contain comment fields. However, uv would assume that these fields...

ZIP Payload Obfuscation Through Parsing Differentials

uv is vulnerable to ZIP payload obfuscation through parsing differentials. The vulnerability is due to improper ZIP archive validation due to failure to reconcile file entries against the central directory, allowing attackers to craft archives with inconsistent or stacked ZIPs that behave...
