Doc Text:
A flaw was found in Oh My Posh. A local attacker could craft a malicious directory name containing a Go template expression. When the prompt renders within this directory or its subdirectories, the embedded template expression could execute arbitrary operating system commands as the current user. This could lead to unauthorized command execution.

Description OSIDB Bzimport 2026-08-13 15:51:22 UTC 
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.
