CVE-2025-55747
XWiki configuration files can be accessed through the webjars API
Impact
### 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. ### References * https://jira.xwiki.org/browse/XWIKI-19350 * https://github.com/xwiki/xwiki-platform/commit/9e7b4c03f2143978d891109a17159f73d4cdd318#diff-45ea9c87d5fb68cd5db0da7f78cf25e76f1325f5fe56e21618b21786fc706236R80-R81 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org)
