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."}],"title":"Duplicate Post <= 1.5.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'noti_token' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c475c51e-f01d-4698-822f-5b8df999bf6d?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L53"},{"url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/menu/notifications.php#L84"},{"url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1598"},{"url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L1601"},{"url":"https://plugins.trac.wordpress.org/browser/copy-delete-posts/tags/1.5.6/post/handler.php#L15"},{"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"},{"url":"https://plugins.trac.wordpress.org/changeset/3709767/copy-delete-posts/trunk/menu/notifications.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":"Kuba"}],"timeline":[{"time":"2026-09-11T18:46:23.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-30T19:57:20.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-01T14:13:40.454787Z","id":"CVE-2026-89424","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-01T14:13:50.290Z"}}]}}
