Description

Impact

This security advisory resolves an XSS vulnerability in image asset names, content language names and future publishing in the back office of the DXP. Back office access and varying levels of editing and management permissions are required to exploit this vulnerability. This typically means Editor or Administrator role, or similar. Injected XSS is persistent and may in some cases be reflected in the front office, possibly affecting end users. The fixes ensure XSS is escaped, and any existing injected XSS is rendered harmless.

Patches

See "Patched versions".

Workarounds

None.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezplatform-admin-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update ezsystems/ezplatform-admin-ui to 2.3.39 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99c7-c3mw-mxhv is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
