This function is registered on the admin_init hook and only checks for the presence of $_POST['submit'] before writing attacker-supplied $_POST['metasync_post_types'] into the site-wide 'metasync_options_instant_indexing' option via update_option(); no current_user_can()/current_user_has_plugin_access() check and no nonce verification are performed. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the site's Google Instant Indexing post-type configuration, controlling which post types are auto-submitted to Google's Instant Indexing service."}],"title":"Search Atlas SEO <= 2.6.23 - Missing Authorization to Authenticated (Subscriber+) Site-Wide Option Modification via 'metasync_post_types' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1bfba54f-961d-4889-9272-0020c9fa0801?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.17/admin/class-metasync-admin.php#L6364"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.17/admin/class-metasync-admin.php#L6358"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.17/admin/class-metasync-admin.php#L384"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.16/admin/class-metasync-admin.php#L6364"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.16/admin/class-metasync-admin.php#L6358"},{"url":"https://plugins.trac.wordpress.org/browser/metasync/tags/2.6.16/admin/class-metasync-admin.php#L384"},{"url":"https://plugins.trac.wordpress.org/changeset/3676919"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","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":"Wordfence PRISM"}],"timeline":[{"time":"2026-09-18T19:15:12.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-15947","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-19T13:24:40.330847Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-19T14:01:24.745Z"}}]}}
