Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
misp-modules, versions up to and including 3.0.7, has unsafe remote resource fetching in its expansion modules. The html_to_markdown module accepts arbitrary HTTP(S) URLs without sufficient validation, enabling Server-Side Request Forgery against loopback, private, or link-local network resources, and the qrcode module disables TLS certificate verification when fetching remote images, allowing possible man-in-the-middle interception. No fixed version is listed.
