Oh My Posh: Arbitrary command execution via template injection in the path segment

Assigner: GitHub_M
Reserved: 12.08.2026 Published: 13.08.2026 Updated: 13.08.2026

Oh My Posh is the most customisable and low-latency cross platform/shell prompt renderer. Prior to 29.35.1, the setStyle() function in src/segments/path.go passed pt.Path, which includes raw folder names, to template.Render, whose function map exposes cmd, so an attacker-controlled directory name containing a Go template expression could execute arbitrary operating system commands as the current user whenever the prompt rendered inside that directory or a descendant. This issue is fixed in version 29.35.1.
