If the workspace contains a repository with preserved attacker-controlled .git/config, the attr.tree setting and a configured clean or process filter can cause Git to run an attacker-controlled program. The program runs outside Codex's command sandbox with the signed-in user's privileges, without a workspace-trust prompt, command approval, or interaction with a model. The attacker can read, modify, or delete files and access credentials available to that user. Exploitation requires Git to be available on PATH and the user to open the attacker-prepared repository with its local Git configuration intact. An ordinary Git clone does not copy the source repository's .git/config and is not sufficient by itself."}],"affected":[{"vendor":"OpenAI","product":"Codex Desktop","platforms":["macOS"],"versions":[{"version":"260202.0859","status":"affected","versionType":"custom","lessThanOrEqual":"26.513.31313"},{"version":"26.519.22136","status":"unaffected"}]},{"vendor":"OpenAI","product":"Codex Desktop","platforms":["Windows"],"versions":[{"version":"26.304.38","status":"affected","versionType":"custom","lessThanOrEqual":"26.513.40821"},{"version":"26.519.21041","status":"unaffected"}]},{"vendor":"OpenAI","product":"Codex Desktop (Microsoft Store package)","platforms":["Windows"],"versions":[{"version":"26.304.38.0","status":"affected","versionType":"custom","lessThanOrEqual":"26.513.4821.0"},{"version":"26.519.2081.0","status":"unaffected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","cweId":"CWE-15","description":"CWE-15: External Control of System or Configuration Setting","type":"CWE"}]}],"references":[{"url":"https://openai.com/codex"}],"credits":[{"lang":"en","value":"Satoki Tsuji (@satoki00) / Ikotas Labs, Inc."}],"configurations":[{"lang":"en","value":"macOS or Windows with Git available on PATH and an attacker-supplied workspace preserving attacker-controlled .git/config, Git attributes, and clean or process filter settings.
