xwiki-platform: Insufficient UI Warning of Dangerous Operations

Published Updated By the CyberSecBulletin desk

CVE-2025-49582 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, < 16.4.7; >= 16.5.0-rc-1, < 16.10.3; >= 17.0.0-rc-1, < 17.0.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.98% chance of exploitation within 30 days, higher than 63% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Xwiki to 16.4.7 or 16.10.3, 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 a generic wiki platform. When editing content that contains "dangerous" macros like malicious script macros that were authored by a user with fewer rights, XWiki warns about the execution of these macros since XWiki 15.9RC1. These required rights analyzers that trigger these warnings are incomplete, allowing an attacker to hide malicious content. For most macros, the existing analyzers don't consider non-lowercase parameters. Further, most macro parameters that can contain XWiki syntax like titles of information boxes weren't analyzed at all. Similarly, the "source" parameters of the content and context macro weren't anylzed even though they could contain arbitrary XWiki syntax. In the worst case, this could allow a malicious to add malicious script macros including Groovy or Python macros to a page that are then executed after another user with programming righs edits the page, thus allowing remote code execution. The required rights analyzers have been made more robust and extended to cover those cases in XWiki 16.4.7, 16.10.3 and 17.0.0.

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.
