CVE-2026-67623: Inclusion of Functionality from Untrusted Control Sphere in mistralai mistral-vibe
Mistral Vibe before 2.23.3 contains a remote code execution vulnerability that allows attackers to execute arbitrary commands by embedding a malicious core.fsmonitor hook in a repository's .git/config file, which is triggered when vibe invokes git status --porcelain without suppressing hook execution. 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.
AI Analysis
Technical Summary
CVE-2026-67623 affects mistral-vibe before version 2.23.3. The vulnerability arises from the inclusion of functionality from an untrusted control sphere via a malicious core.fsmonitor hook embedded in a repository's .git/config file. When mistral-vibe invokes 'git status --porcelain' without disabling hook execution, the malicious hook is triggered, enabling remote code execution with the victim's privileges. This can be exploited by attackers who distribute or create specially crafted repositories containing the malicious fsmonitor entry, causing arbitrary command execution upon running any vibe command within the repository.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands with the victim's full privileges. This can lead to complete compromise of the affected system or environment where mistral-vibe is used. The vulnerability is exploitable without prior authentication and requires user interaction (running vibe commands inside the crafted repository).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid running vibe commands inside untrusted or suspicious repositories that may contain malicious .git/config files with fsmonitor hooks.
