{“lastseen”:””,”description”:”The Spectra Gutenberg Blocks \u2013 Website Builder for the Block Editor plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.19.25.

Exploitation requires a two-block payload embedded in post content: the first block registers a fake uagb\/-prefixed block type with an attacker-specified render_callback, and the second block of the same fake type triggers invocation of that callback via call_user_func() during sequential block rendering in the same page request.”,”published”:”2026-05-30T09:29:00.397Z”,”modified”:”2026-05-30T09:29:00.397Z”,”type”:”cve”,”title”:”Spectra Gutenberg Blocks \\u003c= 2.19.25 – Authenticated (Contributor+) Remote Code Execution via Arbitrary PHP Function Call via Block Attributes”,”source”:”Wordfence”,”references”:”https:\/\/www.wordfence.com\/threat-intel\/vulnerabilities\/id\/60013752-d7cf-46e8-84e1-1b614f737b46?source=cve\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/ultimate-addons-for-gutenberg\/trunk\/classes\/class-uagb-init-blocks.php#L335\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/ultimate-addons-for-gutenberg\/tags\/2.19.25\/classes\/class-uagb-init-blocks.php#L335\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/ultimate-addons-for-gutenberg\/trunk\/classes\/class-uagb-init-blocks.php#L330\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/ultimate-addons-for-gutenberg\/tags\/2.19.25\/classes\/class-uagb-init-blocks.php#L330\\nhttps:\/\/wordpress.org\/plugins\/ultimate-addons-for-gutenberg\/#developers”,”id”:”CVE-2026-7465″,”bulletinFamily”:””,”cwe”:[“CWE-269″],”cvelist”:null,”sourceData”:”brainstormforce Spectra Gutenberg Blocks \u2013 Website Builder for the Block Editor 0″,”sourceHref”:””,”cvss”:{“score”:8.8,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:L\/UI:N\/S:U\/C:H\/I:H\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Spectra Gutenberg Blocks \u2013 Website Builder for the Block Editor”,”version”:”0″,”vendor”:”brainstormforce”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
