{"schema":"threatline.record/2","record":{"id":"CVE-2026-89424","aliases":[],"summary":"Duplicate Post <= 1.5.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'noti_token' Parameter","details":"The Duplicate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'noti_token' parameter in all versions up to, and including, 1.5.6 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. This requires that the site owner has enabled the plugin's User Level Permissions for the Subscriber role, as this grants access to the i_saw_this_noti AJAX branch needed to deliver the payload.","categories":["Unclassified"],"product":"Duplicate Post","vendor":"inisev","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89424","source_modified_at":"2026-10-01T14:13:50.290Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Duplicate Post","vendor":"inisev","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00242,"percentile":0.14565,"score_date":"2026-10-23"},"published_at":"2026-10-01T08:28:45.432Z","modified_at":"2026-10-01T14:13:50.290Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-89424","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T14:13:50.290Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-89424","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c475c51e-f01d-4698-822f-5b8df999bf6d?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L53"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L84"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1598"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1601"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L15"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3709767%40copy-delete-posts%2Ftags%2F1.5.7&old=3652254%40copy-delete-posts%2Ftags%2F1.5.6"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3709767/copy-delete-posts/trunk/menu/notifications.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-01T14:13:40.454787Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T14:13:50.290Z","content_hash":"d39b989d73e09c6a06938940303a4589388b38def0a7f32f8e66e596cdf9639c"}}
