EPSS

• CVE-2024-45591: 3.42% estimated exploitation activity in the next 30 days; percentile 88.91 (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 REST API exposes the history of any page in XWiki of which the attacker knows the name. The exposed information includes for each modification of the page the time of the modification, the version number, the author of the modification (both username and displayed name) and the version comment. This information is exposed regardless of the rights setup, and even when the wiki is configured to be fully private. On a private wiki, this can be tested by accessing /xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome/history, if this shows the history of the main page then the installation is vulnerable. Patches This has been patched in XWiki 15.10.9 and XWiki 16.3.0RC1. Workarounds There aren't any known workarounds apart from upgrading to a fixed version.

# Patch Next advisory brief: CVE-2024-45591

Advisory: XWiki Platform document history including authors of any page exposed to unauthorized actors
IDs: CVE-2024-45591, GHSA-pvmm-55r5-g3mm
Record: https://patchnext.com/advisories/cve-2024-45591 (revision 1, source checked 26 Oct 2026, 16:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
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-rest-server 16.3.0-rc-1, 15.10.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-rest-server: affected >= 1.8.0, < 15.10.9; >= 16.0.0-rc-1, < 16.3.0-rc-1; fixed in 15.10.9, 16.3.0-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-rest-server: 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-rest-server.
- 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-pvmm-55r5-g3mm (GitHub-reviewed advisory GHSA-pvmm-55r5-g3mm lists affected ranges: Maven org.xwiki.platform:xwiki-platform-rest-server >=1.8.0 =16.0.0-rc-1 <16.3.0-rc-1)
