Overview
uv is an An extremely fast Python package and project manager, written in Rust.
Affected versions of this package are vulnerable to Improper Validation of Syntactic Correctness of Input in ZIP archives filenames processing. An attacker can cause malicious code to be executed or files to be extracted differently across Python package installers by crafting a ZIP archive with specially constructed central directory comments or ambiguous filename fields.
