• CVE-2023-35155: 1.50% estimated exploitation activity in the next 30 days; percentile 74.23 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

Impact Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). For instance, the following URL execute an alter on the browser: <xwiki-host/xwiki/bin/view/Main/?viewer=share&send=1&target=&target=%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Crenniepak%40intigriti.me%3E&includeDocument=inline&message=I+wanted+to+share+this+page+with+you., where <xwiki-host is the URL of your XWiki installation. See https://jira.xwiki.org/browse/XWIKI-20370 for me details. Patches The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.4, and 14.4.8. Workarounds The fix is only impacting Velocity templates and page contents, so applying this patch is enough to fix the issue.

# Patch Next advisory brief: CVE-2023-35155

Advisory: XWiki Platform vulnerable to cross-site scripting in target parameter via share page by email
IDs: CVE-2023-35155, GHSA-fwwj-wg89-7h4c
Record: https://patchnext.com/advisories/cve-2023-35155 (revision 1, source checked 26 Oct 2026, 16:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.xwiki.platform:xwiki-platform-sharepage-api 14.10.4, 14.4.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-sharepage-api: affected >= 2.6-rc-2, < 14.4.8; >= 14.5, < 14.10.4; fixed in 14.10.4, 14.4.8

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

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.xwiki.platform:xwiki-platform-sharepage-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-fwwj-wg89-7h4c (GitHub-reviewed advisory GHSA-fwwj-wg89-7h4c lists affected ranges: Maven org.xwiki.platform:xwiki-platform-sharepage-api >=2.6-rc-2 =14.5 <14.10.4)
