Attackers can distribute or create a crafted repository containing a malicious fsmonitor entry to achieve arbitrary command execution with the victim's full privileges when any vibe command is run inside that repository.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-829"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mistralai/mistral-vibe/commit/68ff32e6a92e80a874c8153312f0aa8ae4955477","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/issues/942","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/pull/962","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/pull/978","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/releases/tag/v2.23.3","tags":[]},{"url":"https://therealcoiffeur.com/c111011.html","tags":[]},{"url":"https://www.vulncheck.com/advisories/mistral-vibe-arbitrary-command-execution-via-git-fsmonitor-hook","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/issues/942","tags":[]}],"exploitRefs":[{"url":"https://github.com/mistralai/mistral-vibe/commit/68ff32e6a92e80a874c8153312f0aa8ae4955477","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/issues/942","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/pull/962","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/pull/978","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/releases/tag/v2.23.3","tags":[]},{"url":"https://github.com/mistralai/mistral-vibe/issues/942","tags":[]}],"hasPoc":true,"ai":{"summary":"Mistral Vibe before 2.23.3 allows attackers to execute arbitrary commands via a malicious .git/config file, posing a significant security risk.","exploitability":"Exploitation requires attackers to distribute or create a crafted repository; moderate difficulty due to the need for repository access.","blast_radius":"If exploited, this vulnerability could lead to full system compromise with the victim's privileges across all affected repositories.","remediation":"Update to Mistral Vibe version 2.23.3 or later immediately to mitigate the risk.","tags":["rce","git","repository","update"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-08-11T06:47:55.516Z"}}
