uv before 0.11.15 Arbitrary File Write via Entry Point Names

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

uv before 0.11.15 contains a path traversal vulnerability that allows malicious wheels to write files outside the scripts directory via crafted console_scripts or gui_scripts entry point names. Attackers who induce users to install a malicious wheel can place executables in PATH directories, shadowing or overwriting existing binaries for code execution.

### 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.
