Summary
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.
Risk Assessment
Installing a malicious wheel may lead to overwriting trusted binaries and code execution in the user's or system's context.
Recommendation
Upgrade uv to version 0.11.15 or later and install packages only from trusted sources.
Other vulnerabilities in uv
See all- CVE-2026-114110Medium
Astral uv before 0.11.6 contains a path traversal vulnerability that allows attackers to delete arbitrary files by supplying wheels with relative traversal paths in RECORD entries. A malicious wheel can reference files outside the installation prefix.
- CVE-2026-104843Medium
uv (Python package and project manager) from version 0.12.7 to 0.12.18 has a vulnerability on Windows that allows writing a file outside the installation prefix during extraction of a malicious wheel. This can place an executable in a directory on the user's PATH.
- CVE-2025-13327Medium
A flaw was found in uv. This vulnerability allows an attacker to execute malicious code during package resolution or installation via specially crafted ZIP archives that exploit parsing differentials, requiring user interaction to install an attacker-controlled package.
