This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to demote administrator-owned published builder templates (header, footer, front page, single, archive, 404, and search) to draft status and replace them with attacker-authored block content rendered site-wide, enabling defacement, phishing, and SEO spam. This is possible because the mzb-builder-template post type is registered with capability_type='post' and exposed via the REST API, and the _mzb_template meta key is accessible to any user with edit_posts capability, meaning Contributor-level users and above can trigger the vulnerable save_post() hook.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in Magazine Blocks – Blog Designer, Magazine \u0026 Newspaper Website Builder, Page Builder with Posts Blocks, Post Grid","id":"CVE-2026-75017","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"Missing authorization in Custom Contact Forms","id":"CVE-2026-75018"},"packages":[],"prev":{"headline":"Magazine Blocks \u003c= 1.8.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'clientId' Block Attribute","id":"CVE-2026-75016"},"products":["Magazine Blocks – Blog Designer, Magazine \u0026 Newspaper Website Builder, Page Builder with Posts Blocks, Post Grid"],"published":"2026-09-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["wpblockart"]},"summary":"Authenticated contributors can modify site-wide templates due to missing authorization checks, enabling defacement and phishing attacks.","url":"https://insights.sbomify.com/CVE-2026-75017/"}
