• CVE-2023-50721: 78.81% estimated exploitation activity in the next 30 days; percentile 99.59 (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 The search administration interface doesn't properly escape the id and label of search user interface extensions, allowing the injection of XWiki syntax containing script macros including Groovy macros that allow remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki instance. This attack can be executed by any user who can edit some wiki page like the user's profile (editable by default) as user interface extensions that will be displayed in the search administration can be added on any document by any user. To reproduce, edit any document with the object editor, add an object of type XWiki.UIExtensionClass, set "Extension Point Id" to org.xwiki.platform.search, set "Extension ID" to {{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from extension id succeeded!"){{/groovy}}{{/async}}, set "Extension Parameters" to label={{async}}{{groovy}}services.logging.getLogger("attacker").error("Attack from label…

# Patch Next advisory brief: CVE-2023-50721

Advisory: Remote code execution from account through SearchAdmin
IDs: CVE-2023-50721, GHSA-7654-vfh6-rw6x
Record: https://patchnext.com/advisories/cve-2023-50721 (revision 1, source checked 26 Oct 2026, 16:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
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-search-ui 15.7-rc-1, 15.5.2, 14.10.15. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-search-ui: affected >= 4.5-rc-1, < 14.10.15; >= 15.0-rc-1, < 15.5.2; >= 15.6-rc-1, < 15.7-rc-1; fixed in 14.10.15, 15.5.2, 15.7-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-search-ui: 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-search-ui.
- 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
