The vulnerability resides within the \u003ccode\u003eclient.get\u003c/code\u003e function in the \u003ccode\u003esrc/mcp-server.js\u003c/code\u003e file, which is part of the image-to-base64 endpoint. By manipulating the \u003ccode\u003eurl\u003c/code\u003e argument, a remote attacker can potentially force the server to make requests to unintended locations, including internal resources. This vulnerability, identified as CVE-2026-5346, has a CVSS v3.1 score of 7.3 and is remotely exploitable. Public exploits are available.
