CVE-2026-25481
📋 TL;DR
This vulnerability allows attackers to bypass security controls in Langroid's TableChatAgent and execute arbitrary code through the pandas_eval tool. It affects Langroid applications using TableChatAgent with versions prior to 0.59.32. The bypass occurs due to improper error handling and unrestricted access to dangerous Python attributes.
💻 Affected Systems
- Langroid
📦 What is this software?
Langroid by Langroid
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the environment.
Likely Case
Arbitrary code execution within the Langroid application context, potentially allowing data exfiltration or further privilege escalation.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented, though code execution within the application scope remains possible.
🎯 Exploit Status
Exploitation requires understanding of Python dunder attributes and pandas DataFrame methods to chain attacks. The advisory provides technical details but no public exploit code.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.59.32
Vendor Advisory: https://github.com/langroid/langroid/security/advisories/GHSA-jqq5-wc57-f8hj
Restart Required: Yes
Instructions:
1. Update Langroid to version 0.59.32 or later using pip: 'pip install --upgrade langroid>=0.59.32'. 2. Restart all Langroid applications and services. 3. Verify the update was successful.
🔧 Temporary Workarounds
Disable TableChatAgent pandas_eval
allDisable the vulnerable pandas_eval functionality in TableChatAgent configurations
Modify Langroid configuration to set 'enable_pandas_eval: false' in TableChatAgent settings
Network isolation
allRestrict network access to Langroid applications to trusted sources only
Configure firewall rules to limit inbound connections to Langroid services
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all TableChatAgent inputs
- Run Langroid applications with minimal privileges and in isolated containers or sandboxes
🔍 How to Verify
Check if Vulnerable:
Check Langroid version: 'python -c "import langroid; print(langroid.__version__)"' and verify it's below 0.59.32Check Version:
python -c "import langroid; print(f'Langroid version: {langroid.__version__}')"Verify Fix Applied:
Confirm version is 0.59.32 or higher and test TableChatAgent functionality to ensure pandas_eval works with proper security controls📡 Detection & Monitoring
