This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the site's stored MailUp OAuth tokens in the adfoin_mailup_keys option with attacker-controlled tokens, hijacking future form-submission data to a MailUp account they control or nulling the tokens to break the integration entirely. This is exploitable by any authenticated user who can reach /wp-admin/profile.php, as admin_init fires for all logged-in users visiting any wp-admin page."}],"title":"Advanced Form Integration <= 2.6.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary MailUp OAuth Token Overwrite via auth_redirect() Function","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/af913bb1-eff6-47cd-9471-f74bafda1e52?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.6.0/platforms/mailup/mailup.php#L98"},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.6.0/platforms/mailup/mailup.php#L51"},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.6.0/platforms/mailup/mailup.php#L375"},{"url":"https://plugins.trac.wordpress.org/browser/advanced-form-integration/tags/2.6.0/platforms/mailup/mailup.php#L411"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3621411%40advanced-form-integration&new=3621411%40advanced-form-integration"}],"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":"2026-07-22T14:02:53.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-27T16:35:52.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-28T13:37:44.267126Z","id":"CVE-2026-16587","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":"2026-07-28T14:54:01.926Z"}}]}}
