CVE-2025-65012Network attack vector

Panel session compromise via unescaped model titles

Published Nov 18, 2025 · Updated Nov 19, 2025

Stored cross-site scripting in Content Folder Kirby 5.0.0 through 5.1.3 allows attackers to execute JavaScript in Panel sessions. The Changes dialog inserts attacker-controlled page titles or user names into model-title output without escaping them as plain text. Exploitation requires permission to change a title or name, an unsaved change on that model, and another authenticated Panel user opening the dialog; the script can issue API requests with that user's permissions.
