• CVE-2023-29517: 1.01% estimated exploitation activity in the next 30 days; percentile 63.17 (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 office document viewer macro was allowing anyone to see any file content from the hosting server, provided that the office server was connected and depending on the permissions of the user running the servlet engine (e.g. tomcat) running XWiki. The same vulnerability also allowed to perform internal requests to resources from the hosting server. Patches The problem has been patched in XWiki 13.10.11, 14.10.1, 14.4.8, 15.0-rc-1. Workarounds It might be possible to workaround this vulnerability by running XWiki in a sandbox with a user with very low privileges on the machine, now to run a servlet engine the user will always need access to some files, so in any case this workaround won't protect all files to be accessed.

# Patch Next advisory brief: CVE-2023-29517

Advisory: Exposure of Sensitive Information to an Unauthorized Actor in org.xwiki.platform:xwiki-platform-office-viewer
IDs: CVE-2023-29517, GHSA-m3c3-9qj7-7xmx
Record: https://patchnext.com/advisories/cve-2023-29517 (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 7.5)
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-office-viewer 14.10.1, 14.4.8, 13.10.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-office-viewer: affected >= 2.5-milestone-2, < 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

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-office-viewer: 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-office-viewer.
- 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-m3c3-9qj7-7xmx (GitHub-reviewed advisory GHSA-m3c3-9qj7-7xmx lists affected ranges: Maven org.xwiki.platform:xwiki-platform-office-viewer >=2.5-milestone-2 =14.0-rc-1 =14.5 <14.10.1)
