Description

ApostropheCMS is an open-source Node.js content management system. Versions up to and including 4.29.0 contain an authenticated server-side request forgery (SSRF) in the rich-text widget import flow. An authenticated user who can submit/edit rich-text widget content can cause the server to fetch attacker-controlled URLs during widget validation. For image-compatible responses, the fetched content can be persisted and re-hosted by Apostrophe, allowing response exfiltration. As of time of publication, no known patched versions are available.
