This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The sanitization bypass is possible because the save_meta_data() handler returns early when $_POST['post_type'] is absent — a condition always true during XML-RPC requests — and the plugin unconditionally grants Subscribers the publish_aiovg_videos capability, making this exploitable by any authenticated user via a single wp.newPost XML-RPC call."}],"title":"All-in-One Video Gallery <= 4.9.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'embedcode' Post Meta via XML-RPC","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cc6b1fa7-d5f9-4aec-860e-067c26745450?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/includes/player/base.php#L1028"},{"url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/includes/player/base.php#L277"},{"url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/admin/videos.php#L254"},{"url":"https://plugins.trac.wordpress.org/changeset/3759353/all-in-one-video-gallery/trunk/includes/player/base.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"poiri3r"}],"timeline":[{"time":"2026-10-12T13:45:35.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-27T14:29:11.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-109209","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-29T01:32:22.661683Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-29T01:51:59.353Z"}}]}}
