Description

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

uv 0.11.15 and newer address this vulnerability. Users are encouraged to upgrade to 0.11.15.

Workarounds

There is no workaround other than upgrading to uv 0.11.15.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for uv, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update uv to 0.11.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4gg8-gxpx-9rph is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
