Claude Desktop: Uncontrolled Search Path Enables Arbitrary Code Execution via Malicious Git Executable

Summary

Claude Desktop is Anthropic's desktop application for interacting with Claude. Prior to 1.8089.0, Claude Desktop on Windows invokes git.exe through uv_spawn without an absolute path, allowing Windows search-path resolution to select a malicious git.exe placed in the opened project's current working directory before the intended system executable. Opening an attacker-controlled or shared repository can therefore execute the substituted program with the user's privileges. This issue is fixed in version 1.8089.0.

Remediation
