Detailsinfo

A vulnerability, which was classified as very critical, was found in ltdrdata ComfyUI-Manager up to 2.51.0. This affects some unknown processing of the file /customnode/install of the component POST Request Handler. The manipulation of the argument pip with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The issue stems from a missing validation of the pip field in a POST request sent to the /customnode/install endpoint used to install custom nodes which is added to the server by the extension. This allows an attacker to craft a request that triggers a pip install on a user controlled package or URL, resulting in remote code execution (RCE) on the server.
