CVE-2025-49583 Details
Description
XWiki is a generic wiki platform. When a user without script right creates a document with an `XWiki.Notifications.Code.NotificationEmailRendererClass` object, and later an admin edits and saves that document, the email templates in this object will be used for notifications. No malicious code can be executed, though, as while these templates allow Velocity code, the existing generic analyzer already warns admins before editing Velocity code. The main impact would thus be to send spam, e.g., with phishing links to other users or to hide notifications about other attacks. Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. This has been patched in XWiki 16.10.2, 16.4.7 and 15.10.16 by adding an analysis for the respective XClass properties.
A vulnerability exists in XWiki versions prior to 15.10.16, 16.0.0-rc-1 through 16.4.7, and 16.5.0-rc-1 through 16.10.2. When a user without script rights creates a document containing an 'XWiki.Notifications.Code.NotificationEmailRendererClass' object, and an admin later edits and saves that document, the email templates from this object are applied to notifications. Although these templates can include Velocity code, a built-in generic analyzer alerts admins before they edit such code, preventing any execution of malicious scripts. The primary consequence of this vulnerability is the potential to misuse the email templates for spamming, such as sending phishing links to other users or obscuring notifications about other security incidents.
Users can upgrade to XWiki versions 15.10.16, 16.4.7, or 16.10.2, where this vulnerability has been patched. For those using versions 15.9-rc-1, it is advisable to exercise caution when editing documents created by users with script rights.
