langchain@0.2.5 vulnerabilities

langchain is a Building applications with LLMs through composability

Affected versions of this package are vulnerable to Server-Side Request Forgery (SSRF) through the Web Research Retriever component. An attacker can execute port scans, access local services, and potentially read instance metadata from cloud environments by sending crafted requests to the server.

Note: This SSRF vulnerability makes it possible to scan ports, abuse the Web Explorer server as a proxy for attacks on third parties and interact with servers in the local network including reading their response data, which may allow to extract instance metadata if in a cloud environment. The attack consequences of interacting with local services depends heavily on the nature of these services. Regularly admin-privileged services are exposed locally on servers, so the consequences can go all the way up to arbitrary code execution. Sending POST requests is not possible, only GET, but integrity may still be affected as a result of stolen credentials or because especially on internal APIs also GET requests can be state-changing. For all these reasons, the Confidentiality, Integrity, Availability metrics are set to H, L, L, the result is not an uncommon score for SSRF vulnerabilities.

There is no fixed version for langchain.
