CVE-2026-62414 Overview
CVE-2026-62414 is an improper access control vulnerability in the Joomla extension Page Builder CK, developed by joomlack.fr. The flaw affects all versions of Page Builder CK prior to 3.6.2. The extension fails to enforce access control on frontend page list views, allowing unauthenticated remote attackers to view and interact with content that should be restricted. The weakness is classified as [CWE-284] Improper Access Control. The vulnerability is exploitable over the network without authentication or user interaction.
Critical Impact
Unauthenticated remote attackers can bypass frontend access controls in Page Builder CK to disclose and manipulate restricted page list data.
Affected Products
- Joomla Extension: Page Builder CK by joomlack.fr
- All versions prior to 3.6.2
- Joomla sites exposing frontend page list views via Page Builder CK

Technical Details for CVE-2026-62414
Vulnerability Analysis
Page Builder CK is a Joomla extension used to construct frontend pages through modular content blocks. The extension exposes list views that render page content on the frontend. In versions before 3.6.2, these list views do not verify user access rights before returning content. Attackers can request the list view endpoints directly and receive data intended for privileged users. The confidentiality and integrity impacts are high, while availability is not affected, according to the published CVSS vector. The weakness maps to [CWE-284] Improper Access Control.
Root Cause
The root cause is missing authorization enforcement in the frontend page list view controllers. The extension trusts request parameters and view routing without validating whether the requesting session has permission to view or modify the referenced resources. Access control checks that exist in the Joomla core ACL model are not invoked for these endpoints.
Attack Vector
An unauthenticated attacker reaches the vulnerable endpoints over HTTP or HTTPS. The attacker issues crafted requests to the frontend page list view of a Joomla site running a vulnerable Page Builder CK version. Because no authentication, no user interaction, and low attack complexity are required, the endpoints can be enumerated using standard web tooling. No public proof-of-concept or exploit code is currently available.
No verified exploit code is available. See the Joomlack Security Resources for vendor guidance and technical details.
Detection Methods for CVE-2026-62414
Indicators of Compromise
- Unauthenticated HTTP requests to Page Builder CK frontend list view routes from unfamiliar source IP addresses.
- Unexpected access to content items that were configured as restricted or unpublished.
- Web server access logs showing enumeration of com_pagebuilderck view parameters.
Detection Strategies
- Inventory Joomla installations and enumerate installed extensions to identify Page Builder CK versions below 3.6.2.
- Review Joomla administrator logs and web server logs for anomalous requests targeting Page Builder CK list view endpoints.
- Correlate authentication state with access to protected content to identify unauthenticated retrieval of restricted resources.
Monitoring Recommendations
- Enable verbose HTTP access logging on Joomla frontends and forward logs to a centralized SIEM.
- Alert on spikes in requests to Page Builder CK URLs from single source addresses or automated user agents.
- Monitor for outbound data volume anomalies from Joomla webservers that could indicate bulk content scraping.
How to Mitigate CVE-2026-62414
Immediate Actions Required
- Upgrade Page Builder CK to version 3.6.2 or later on all Joomla installations.
- Audit content items that may have been exposed through unauthorized list view access.
- Restrict access to Joomla administrator and extension endpoints using web application firewall rules until patching is complete.
Patch Information
The vendor addresses this vulnerability in Page Builder CK version 3.6.2. Administrators should download the fixed release from the vendor and apply it through the Joomla extension manager. Refer to the Joomlack Security Resources for the official release notes and download links.
Workarounds
- Temporarily disable the Page Builder CK extension in the Joomla extension manager until the update is applied.
- Block requests to Page Builder CK frontend view routes at the web application firewall or reverse proxy.
- Restrict frontend access to authenticated users through web server authentication controls where feasible.
