DescriptionCVE.org
Wagtail is an open source content management system built on Django. In versions prior to 7.0.8, 7.3.3 and 7.4.2, the Documents and Images chooser's chosen endpoint incorrectly listed items for which the user has not been granted choose permission. A user with access to the Wagtail admin could see the filename and name and URLs of documents and images in those collections. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. This issue has been fixed in versions 7.0.8, 7.3.3, and 7.4.2.
AnalysisAI
Wagtail's Documents and Images chooser endpoint leaks asset metadata - including filenames, display names, and URLs - to authenticated admin users who have been explicitly denied collection-level choose permissions. Versions prior to 7.0.8, 7.3.3, and 7.4.2 are affected across the 7.0, 7.3, and 7.4 release branches. An attacker with a valid Wagtail admin account can enumerate restricted media assets across collections beyond their authorized scope, bypassing the collection permission model. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis.
Technical ContextAI
Wagtail is a Django-based open-source CMS (cpe:2.3:a:wagtail:wagtail) widely used for editorial and publishing workflows. The vulnerability resides in the 'chosen' API endpoint of the Documents and Images chooser widget - a server-side component used during content editing to allow editors to select media assets. The root cause class is CWE-280 (Improper Handling of Insufficient Permissions or Privileges): the endpoint returns asset listings without enforcing the collection-specific 'choose' permission, meaning the server-side authorization check is either absent or misapplied for this code path. This is a broken access control issue in the chooser's query layer, not an injection or client-side flaw. The Django permission framework supports granular collection-level restrictions in Wagtail, but this endpoint bypasses those controls.
RemediationAI
Upgrade Wagtail to one of the patched releases confirmed by the vendor advisory: 7.0.8 (for 7.0.x deployments), 7.3.3 (for 7.3.x deployments), or 7.4.2 (for 7.4.x deployments), as detailed at https://github.com/wagtail/wagtail/security/advisories/GHSA-h54r-xq46-qwqm. No workaround patches the endpoint's missing permission check without upgrading. If immediate upgrade is not operationally possible, the most targeted compensating control is to audit current admin user accounts and temporarily revoke admin interface access for any accounts that should not have visibility into restricted collections - accepting the trade-off that those users lose all admin functionality until the patch is applied. Generic network-level controls (WAF rules, IP allowlisting) will not mitigate this flaw since it requires authenticated admin access by design.
