Description

Impact

It's possible to display any page you cannot access through the combination of the async and display macro.

Steps to reproduce:

  1. Enable comments for guests by giving guests comment rights
  2. As a guest, create a comment with content {{async}}{{display reference="Menu.WebHome" /}}{{/async}}
  3. Open the comments viewer from the menu (appends ?viewer=comments to the URL)

-> the Menu.WebHome is displayed while the expectation would be to have an error that the current user is not allowed to see it

Patches

The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11.

Workarounds

There is no known workaround.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-oldcore. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update org.xwiki.platform:xwiki-platform-oldcore to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gpq5-7p34-vqx5 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-gpq5-7p34-vqx5 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-gpq5-7p34-vqx5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
