LibreChat is a ChatGPT clone with additional features. Version 0.8.1-rc2 is prone to a server-side request forgery (SSRF) vulnerability due to missing restrictions of the Actions feature in the default configuration. LibreChat enables users to configure agents with predefined instructions and actions that can interact with remote services via OpenAPI specifications, supporting various HTTP methods, parameters, and authentication methods including custom headers. By default, there are no restrictions on accessible services, which means agents can also access internal components like the RAG API included in the default Docker Compose setup. This issue is fixed in version 0.8.1-rc2.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.1, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), limited integrity, and limited availability for affected systems. Impacting 1 product from librechat organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For librechat's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
