CVE-2026-110225

Açıklama (NVD)

Shaarli through 0.16.9 contains a server-side request forgery vulnerability that allows authenticated users to make the server request internal addresses by fetching bookmark thumbnails without private-address checks. Attackers can create bookmarks pointing to loopback, private, or cloud metadata addresses and trigger ThumbnailsController::ajaxUpdate or saving to send blind GET requests, with open_shaarli exposing this to any visitor.
