xwiki-platform: Relative Path Traversal
CVE-2025-55748 is a high-severity relative path traversal vulnerability in xwiki-platform from XWiki, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected xwiki-platform versions: >= 4.2-milestone-2, < 16.10.7. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.84% chance of exploitation within 30 days, higher than 79% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Xwiki to 16.10.7 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions 4.2-milestone-2 through 16.10.6, configuration files are accessible through jsx and sx endpoints. It's possible to access and read configuration files by using URLs such as `http://localhost:8080/bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false`. This is fixed in version 16.10.7.

The underlying weakness: Relative Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
