uv: Path traversal on Windows through wheel extraction

### Impact In versions of uv from 0.12.7 to 0.12.18 on Windows, uv could be induced into writing a file outside of the installation prefix during wheel installation. 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 vulnerability only affects Windows hosts; no other platforms are affected. ### Patches uv 0.12.18 and newer address this vulnerability. Users are encouraged to upgrade t

uv allows ZIP payload obfuscation through parsing differentials

## Impact In versions 0.8.5 and earlier of uv, remote ZIP archives were handled in a streamwise fashion, and file entries were not reconciled against the archive's central directory. This enabled two parser differentials against other Python package installers: 1. An attacker could contrive a ZIP archive that would extract with legitimate contents on some package installers, and malicious contents on others due to multiple local file entries. The attacker could choose which installer to target

uv is vulnerable to arbitrary file write through entry point names

### 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 overwr

uv vulnerable to arbitrary file deletion through RECORD entries

## Impact Wheel RECORD entries can contain relative paths that traverse outside of the wheel’s installation prefix. In versions 0.11.5 and earlier of uv, these wheels were not rejected on installation and the RECORD was respected without validation on uninstall. uv uses the RECORD to determine files to remove on uninstall. Consequently, a malicious or malformed wheel could induce deletion of arbitrary files outside of the wheel’s installation prefix on uninstall. uv does not use the RECORD fi

PYSEC-2026-2295

A flaw was found in uv. This vulnerability allows an attacker to execute malicious code during package resolution or installation via specially crafted ZIP (Zipped Information Package) archives that exploit parsing differentials, requiring user interaction to install an attacker-controlled package.
