Page rendering failure via malformed translation object

Published Apr 18, 2023 · Updated Feb 5, 2025

Uncaught exception in XWiki Platform allows remote authenticated users to break page rendering by saving a malformed translation object. The wiki-localization source does not catch the exception raised while loading the malformed document, so translation lookup and page rendering fail. Page-edit permission is required; affected translations stop rendering, with no reported code execution or data disclosure.
