[ Description ]Official description
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.
