GHSA-75MJ-4G74-9RG2

Vulnerability from github – Published: 2025-12-13 18:30 – Updated: 2025-12-13 18:30

Details

The vulnerability arises when a client fetches a tools’ JSON specification, known as a Manual, from a remote Manual Endpoint. While a provider may initially serve a benign manual (e.g., one defining an HTTP tool call), earning the clients’ trust, a malicious provider can later change the manual to exploit the client.

Severity ?

7.5 (High)
