CVE-2026-114109 Details
Description
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.
A path traversal vulnerability has been identified in the 'uv' package, affecting versions prior to 0.11.15. This vulnerability allows malicious wheels to write files outside the designated scripts directory by exploiting crafted entry point names in 'console_scripts' or 'gui_scripts'. Attackers can manipulate users into installing these malicious wheels, potentially placing executable files in directories included in the user's PATH. This could overwrite existing binaries or shadow them, leading to unauthorized code execution.
Users are advised to upgrade to 'uv' version 0.11.15 or later.
