EPSS

• CVE-2025-55747: 1.75% estimated exploitation activity in the next 30 days; percentile 77.89 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2025-55747

Advisory: XWiki configuration files can be accessed through the webjars API
IDs: CVE-2025-55747, GHSA-qww7-89xh-x7m7
Record: https://patchnext.com/advisories/cve-2025-55747 (revision 1, source checked 26 Oct 2026, 16:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.xwiki.platform:xwiki-platform-webjars-api 17.4.0-rc-1, 16.10.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-webjars: affected >= 6.1-miletone-2, <= 7.1.3
- Maven org.xwiki.platform:xwiki-platform-webjars-api: affected >= 7.1.4, < 16.10.7; >= 17.0.0-rc-1, < 17.4.0-rc-1; fixed in 16.10.7, 17.4.0-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-webjars: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-webjars-api: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.xwiki.platform:xwiki-platform-webjars, org.xwiki.platform:xwiki-platform-webjars-api.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qww7-89xh-x7m7 (GitHub-reviewed advisory GHSA-qww7-89xh-x7m7 lists affected ranges: Maven org.xwiki.platform:xwiki-platform-webjars-api >=7.1.4 =17.0.0-rc-1 =6.1-miletone-2 <=7.1.3)
