HighCVSS 8.8Summary
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.
