• CVE-2023-29515: 0.57% estimated exploitation activity in the next 30 days; percentile 47.06 (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 Any user who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening /xwiki/bin/view/AppWithinMinutes/CreateApplication?wizard=true on the XWiki installation. Patches This has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1 by not granting the space admin right if the user doesn't have script right on the space where the app is created. Error message are displayed to warn the user that the app will be broken in this case. Users who became space admin through this vulnerability won't loose the space admin right due to the fix, so it is advised to check if all users who created AWM apps should keep their space admin rights. Workarounds The patch can be applied by…

# Patch Next advisory brief: CVE-2023-29515

Advisory: XWiki App Within Minutes app grants space admin rights that allows cross-site scripting
IDs: CVE-2023-29515, GHSA-44h9-xxvx-pg6x
Record: https://patchnext.com/advisories/cve-2023-29515 (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: Medium (CVSS 5.4)
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-appwithinminutes-ui 14.10.1, 14.4.8, 13.10.11; org.xwiki.platform:xwiki-platform-appwithinminutes 4.2-milestone-1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-appwithinminutes-ui: affected >= 4.2-milestone-1, < 13.10.11; >= 14.0-rc-1, < 14.4.8; >= 14.5, < 14.10.1; fixed in 13.10.11, 14.10.1, 14.4.8
- Maven org.xwiki.platform:xwiki-platform-appwithinminutes: affected >= 4.0-milestone-2, < 4.2-milestone-1; fixed in 4.2-milestone-1

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