FKIE_CVE-2026-73505

Vulnerability from fkie_nvd - Published: 2026-08-13 15:20 - Updated: 2026-08-13 16:19
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
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.
