xwiki-platform: Insufficient UI Warning of Dangerous Operations

CVE-2025-49587 is a high-severity insufficient UI warning of dangerous operations vulnerability in xwiki-platform from XWiki, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected xwiki-platform versions: >= 15.9-rc-1, < 15.10.16; >= 16.0.0-rc-1, < 16.4.7; >= 16.5.0-rc-1, < 16.10.2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.

High severity with no evidence of exploitation so far.

What to do

  1. Update Xwiki to 15.10.16 or 16.4.7 or 16.10.2, whichever matches your release line, or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

XWiki is an open-source wiki software platform. When a user without script right creates a document with an XWiki.Notifications.Code.NotificationDisplayerClass object, and later an admin edits and saves that document, the possibly malicious content of that object is output as raw HTML, allowing XSS attacks. While the notification displayer executes Velocity, the existing generic analyzer already warns admins before editing Velocity code. 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 vulnerability has been patched in XWiki 15.10.16, 16.4.7, and 16.10.2 by adding a required rights analyzer that warns the admin before editing about the possibly malicious code.

The underlying weakness: Insufficient UI Warning of Dangerous Operations

The user interface provides a warning to a user regarding dangerous or sensitive operations, but the warning is not noticeable enough to warrant attention.
