This is due to a mismatch between the object used for authorization and the object actually accessed in the Optimize_Rest_Controller's create_item(), get_item(), delete_item(), and bulk_delete_items() endpoints — authorization is checked via current_user_can('edit_post'/'delete_post', $post_id) against the user-supplied post_id, while the storage layer keys analysis records on sha256($post_path) from a separately supplied, attacker-controlled post_path parameter, with no enforcement that post_path corresponds to post_id. This makes it possible for authenticated attackers, with Contributor-level access and above, to read or delete optimizer analysis records belonging to posts owned by other users by submitting their own post_id (which passes the capability check) together with the victim post's path."}],"title":"Kadence Blocks <= 3.7.7 - Insecure Direct Object Reference to Authenticated (Contributor+) Arbitrary Optimizer Data Deletion/Read/Modification via 'post_path' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/24cdd50f-742c-457c-85f7-9cccaf366e87?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L232"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L458"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L197"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L420"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L153"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L383"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L339"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Store/Table_Store.php#L96"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.7.6/includes/resources/Optimizer/Path/Path.php#L60"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L232"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L458"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L197"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L420"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L153"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L383"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L339"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Store/Table_Store.php#L96"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Path/Path.php#L60"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3590217%40kadence-blocks&new=3590217%40kadence-blocks&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"se1en"}],"timeline":[{"time":"2026-06-22T14:49:11.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-06-30T14:57:59.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-12904","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-07-01T10:32:05.309457Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-01T10:42:11.715Z"}}]}}
