🛡️ CVE-2025-55747 — xwiki

🔴 CVSS 9.5 — Critical ✅ No Known Exploit CWE-23 NVD
9.5
CVSS Score
0 Low4 Medium7 High9 Critical10

Description

XWiki configuration files can be accessed through the webjars API

Impact

It's possible to get access and read configuration files by using URLs such as http://localhost:8080/xwiki/webjars/wiki%3Axwiki/..%2F..%2F..%2F..%2F..%2FWEB-INF%2Fxwiki.cfg. The trick here is to encode the / which is decoded when parsing the URL segment, but not re-encoded when assembling the file path.

Patches

This has been patched in 17.4.0-rc-1, 16.10.7.

Workarounds

There is no known workaround, other than upgrading XWiki.
