{"schema":"threatline.record/2","record":{"id":"CVE-2026-109209","aliases":[],"summary":"All-in-One Video Gallery <= 4.9.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'embedcode' Post Meta via XML-RPC","details":"The All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_fields[embedcode]' parameter in all versions up to, and including, 4.9.7 due to insufficient input sanitization and output escaping. 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.","categories":["Unclassified"],"product":"All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos","vendor":"plugins360","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109209","source_modified_at":"2026-10-28T02:29:59.405Z","fetched_at":"2026-10-28T08:18:35.509402Z","product":"All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos","vendor":"plugins360","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.9.7","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T02:29:59.405Z","modified_at":"2026-10-28T02:29:59.405Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109209","fetched_at":"2026-10-28T08:18:35.509402Z","source_modified_at":"2026-10-28T02:29:59.405Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cc6b1fa7-d5f9-4aec-860e-067c26745450?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/includes/player/base.php#L1028"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/includes/player/base.php#L277"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/all-in-one-video-gallery/tags/4.9.7/admin/videos.php#L254"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3759353/all-in-one-video-gallery/trunk/includes/player/base.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T02:29:59.405Z","content_hash":"92382d6d51132a2a772e38f20124e52bfd151c86f3230a73fe41b84aa8917898"}}
