BdThemes ZoloBlocks: Broken access control (missing authorization)
Summary
The ZoloBlocks WordPress plugin up to and including version 2.8.2 lacks an authorization check, which allows functionality to be reached that should be restricted. According to the CVE record, the flaw can be exploited without authentication over the network. The published impact is rated low for confidentiality and none for integrity and availability, and the exact data or actions exposed are not described in the sources.

- Version 2.8.3 is not explicitly addressed in the sources; treat it as affected until confirmed

Our recommendation
- Inventory WordPress sites with ZoloBlocks installed and record their versions
- Update to 2.8.4 or later, prioritising internet-facing sites, and confirm the installed version afterwards
- If a site cannot be updated soon, consider deactivating the plugin until it is patched
- Review the Patchstack entry and BdThemes release notes once available and verify the fix version
- Track ZoloBlocks security notices, as several missing-authorization CVEs have affected this plugin before (CVE-2025-12134, CVE-2025-49903)
