An authenticated attacker can bypass regex-based source-code filtering by leveraging Python object hierarchy traversal and runtime bytecode manipulation, leading to arbitrary code execution as the process owner.\n\n## TL;DR\nAn authenticated RCE vulnerability exists in LiteLLM's `/guardrails/test_custom_code` endpoint. The custom Python sandbox relies on flawed regex filtering, allowing attackers to rewrite function bytecode and access restricted built-ins to execute system commands.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-94\n- **Attack Vector**: Network\n- **CVSS v3.1 Score**: 8.8\n- **EPSS Score**: 0.0024\n- **Impact**: Remote Code Execution\n- **Exploit Status**: Proof of Concept (PoC)\n\n## Affected Systems\n\n- LiteLLM Proxy\n- LiteLLM Docker Containers\n- **LiteLLM**: <= 2026-04-08 (Fixed in: `v1.83.10-stable`)\n\n## Mitigation\n\n- Software Update\n- Network Segmentation\n- Privilege Reduction\n- URI Blocking\n\n**Remediation Steps:**\n1.
