CVE-2025-55747: XWiki configuration files can be accessed through the webjars API

September 3, 2025

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.
