CVE-2026-2008
📋 TL;DR
This CVE describes a code injection vulnerability in the abhiphile fermat-mcp project's eqn_chart function. Attackers can remotely exploit this by manipulating equation arguments to execute arbitrary code. All users of fermat-mcp up to commit 47f11def1cd37e45dd060f30cdce346cbdbd6f0a are affected.
💻 Affected Systems
- abhiphile fermat-mcp
📦 What is this software?
Fermat by Abhiphile
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Remote code execution allowing attackers to run arbitrary commands on affected systems, potentially leading to data exfiltration or system disruption.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented, potentially only causing denial of service.
🎯 Exploit Status
The exploit is publicly available and can be initiated remotely without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch is available. Monitor the GitHub repository for updates and apply any security patches when released.
🔧 Temporary Workarounds
Disable or remove vulnerable component
allDisable or remove the eqn_chart functionality if not required for your use case
# Remove or comment out eqn_chart.py usage in your codebase
Input validation and sanitization
allImplement strict input validation for equation arguments before passing to eqn_chart function
# Add input validation logic before calling eqn_chart()
🧯 If You Can't Patch
- Network segmentation: Isolate systems running fermat-mcp from critical infrastructure
- Implement strict network access controls and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if your fermat-mcp installation uses commit 47f11def1cd37e45dd060f30cdce346cbdbd6f0a or earlier: git log --oneline | head -20Check Version:
git log --oneline | head -1Verify Fix Applied:
Verify the repository has been updated beyond the vulnerable commit: git log --oneline | grep -A5 '47f11def1cd37e45dd060f30cdce346cbdbd6f0a'📡 Detection & Monitoring
