Wagtail vulnerable to stored Cross-site Scripting attack via ModelAdmin views

CVE-2023-28836GHSA-5286-f2rf-35c2

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (wagtail 4.2.2, 4.1.4), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact A stored cross-site scripting (XSS) vulnerability exists on ModelAdmin views within the Wagtail admin interface. A user with a limited-permission editor account for the Wagtail admin could potentially craft pages and documents that, when viewed by a user with higher privileges, could perform actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin, and only affects sites with ModelAdmin enabled. - For page, the vulnerability is in the "Choose a parent page" ModelAdmin view (ChooseParentView), available when managing pages via ModelAdmin. - For documents, the vulnerability is in the ModelAdmin Inspect view (InspectView) when displaying document fields. Patches Patched versions have been released as Wagtail 4.1.4 (for the LTS 4.1 branch) and Wagtail 4.2.2 (for the current 4.2 branch). Workarounds Site owners who are unable to upgrade to the new versions can disable or override the corresponding…

# Patch Next advisory brief: CVE-2023-28836

Advisory: Wagtail vulnerable to stored Cross-site Scripting attack via ModelAdmin views
IDs: CVE-2023-28836, GHSA-5286-f2rf-35c2
Record: https://patchnext.com/advisories/cve-2023-28836 (revision 3, source checked 26 Oct 2026, 13:27 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: wagtail 4.2.2, 4.1.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI wagtail: affected >= 1.5, < 4.1.4; >= 4.2, < 4.2.2; fixed in 4.2.2, 4.1.4

## Suggested inspection (read-only)
- `python -m pip show wagtail`: prints the installed version. Run with the environment that serves production active.

## 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 wagtail.
- 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.
