Description
Impact
A stored Cross-site Scripting (XSS) vulnerability exists on confirmation messages within the wagtail.contrib.simple_translation module. A user with access to the Wagtail admin area may create a page with a specially-crafted title which, when another user performs the "Translate" action, causes arbitrary JavaScript code to run. This could lead to performing actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
Patches
Patched versions have been released as Wagtail 6.3.8, 7.0.6, 7.2.3 and 7.3.1.
Workarounds
None

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wagtail, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update wagtail to 6.3.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p4v8-rw59-93cq is resolved across your whole dependency graph.
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.
