The Brizy WordPress plugin before 2.8.18 does not properly verify authorization on a request handler before returning post content, allowing users with the Contributor role or higher to read the content of arbitrary posts, including other users' private, pending, and draft posts.
AnalysisAI
Improper authorization in the Brizy WordPress plugin before 2.8.18 allows any authenticated user holding the Contributor role or above to read the full content of arbitrary posts, bypassing WordPress's native visibility controls for private, pending, and draft posts. The flaw resides in a specific request handler that returns post content without verifying whether the requesting user is entitled to view it (CWE-639, IDOR). A publicly available proof-of-concept exploit has been published by WPScan; however, no confirmed active exploitation appears in CISA KEV, and the EPSS score of 0.13% (3rd percentile) reflects limited observed exploitation activity at time of analysis.
Technical ContextAI
Brizy is a drag-and-drop page builder plugin for WordPress. The vulnerability is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), a class of Insecure Direct Object Reference (IDOR) flaw where a server-side request handler returns content based on a caller-supplied identifier - in this case a post ID or similar key - without confirming the caller holds read permission for that object. WordPress natively restricts visibility of posts in 'private', 'draft', and 'pending' status to their authors and privileged roles (Editor/Administrator). The Brizy plugin's request handler bypasses this model by responding with content to any authenticated request, regardless of the requester's relationship to the post. The affected CPE is cpe:2.3:a:unknown:brizy:*:*:*:*:*:*:*:* covering all versions before 2.8.18.
RemediationAI
Vendor-released patch: Brizy version 2.8.18. Site administrators should update the Brizy plugin to 2.8.18 or later immediately via the WordPress dashboard or wp-cli. The WPScan advisory at https://wpscan.com/vulnerability/2ed270b0-c01e-4615-b365-3455c161a2d9/ confirms this fix version. If an immediate upgrade is not feasible, a compensating control is to temporarily revoke or limit Contributor-role accounts on the site, particularly for untrusted external contributors, noting this disrupts publishing workflows. Restricting access to the vulnerable request handler endpoint via WAF rules targeting the specific Brizy AJAX action (if identifiable from the POC) is a second compensating option, though the handler's exact endpoint name is not specified in available data.
