CVE-2026-44738Public exploitNetwork attack vector

Plugin-secret disclosure via sandboxed config.toArray call

Published May 11, 2026 · Updated May 11, 2026

Information disclosure in Grav before 2.0.0-rc.2 allows remote authenticated users with admin.pages to read all plugin secrets. The Twig sandbox injects the merged configuration into page renders and allows Config::toArray() to serialize sensitive plugin settings into HTML. An editor must enable Twig processing in a page and insert the call; the output exposes stored passwords, access keys, client secrets, and API tokens.
