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, specifically a malicious core.fsmonitor hook embedded in a repository's .git/config file. When mistral-vibe executes 'git status --porcelain', it does not suppress hook execution, allowing the malicious hook to run arbitrary commands. This enables remote code execution with the privileges of the user running the software. The vulnerability requires the attacker to distribute or create a crafted repository containing the malicious fsmonitor entry.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary commands remotely with the full privileges of the victim user running mistral-vibe. This can lead to complete compromise of the affected system or environment where the software is used.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid running mistral-vibe commands inside untrusted or suspicious repositories that may contain malicious .git/config hooks.
