# CVE-2026-73505: Oh My Posh: Arbitrary command execution via template injection in the path segment

- Also known as: GHSA-6XJ8-QV9J-XCJQ, GO-2026-6108
- Severity: CVSS 7.8 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 29.35.1, 29.35.1+incompatible
- Published: 2026-08-13 · Updated: 2026-08-13

## Affected

- JanDeDobbeleer oh-my-posh: fixed in 29.35.1
- github.com/jandedobbeleer/oh-my-posh (Go): fixed in 29.35.1
- github.com/jandedobbeleer/oh-my-posh (Go): fixed in 29.35.1+incompatible

## Description

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.

## What to do

- Check your stack: if you ship or depend on JanDeDobbeleer oh-my-posh, github.com/jandedobbeleer/oh-my-posh, upgrade to a fixed version (29.35.1, 29.35.1+incompatible) per the references below.
