Vulnerability GHSA-4gg8-gxpx-9rph

Impact

In versions of uv prior to 0.11.15, when installing a distribution containing an entry point specification (under console_scripts or gui_scripts), uv would place the generated entry point according to the given name even if doing so resulted in a path outside of the environment's scripts directory.

A malicious wheel could use this to place an executable outside of the intended environment, including in a directory already present on the user's PATH. This could shadow or overwrite an existing executable and potentially result in unexpected code execution under the wheel's control, even if the wheel's installation environment was not explicitly added to PATH by the user.

In order to exploit this vulnerability, the attacker must induce their target into installing a malicious wheel.

Patches

Workarounds
