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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Path/Path.php#L60","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L153","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L197","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L232","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.6.7/includes/resources/Optimizer/Rest/Optimize_Rest_Controller.php#L339"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-12904","score":0.00451,"percentile":0.39215,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
