{"id":"CVE-2025-12887","state":"PUBLISHED","title":"Post SMTP – Complete SMTP Solution with Logs, Alerts, Backup SMTP & Mobile App <= 3.6.1 - Missing Authorization to Authenticated (Subscriber+) OAuth Token Update","description":"The Post SMTP plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.6.1. This is due to the plugin not properly verifying that a user is authorized to update OAuth tokens on the 'handle_gmail_oauth_redirect' function. This makes it possible for authenticated attackers, with subscriber level access and above, to inject invalid or attacker-controlled OAuth credentials. CVE-2025-67563 appears to be a duplicate of this issue.","publishedAt":"2025-12-03T12:29:53.626Z","updatedAt":"2026-04-08T16:55:27.472Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","source":"Wordfence"},"assigner":"Wordfence","products":["saadiqbal Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App"],"affected":[{"vendor":"saadiqbal","product":"Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.6.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5bd9f312-99e1-4dc2-855d-90339c2e24da?source=cve","https://plugins.trac.wordpress.org/changeset/3402203"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/12xxx/CVE-2025-12887.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-12887","state":"PUBLISHED","datePublished":"2025-12-03T12:29:53.626Z","dateUpdated":"2026-04-08T16:55:27.472Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-11-07T17:28:03.418Z"},"containers":{"cna":{"title":"Post SMTP – Complete SMTP Solution with Logs, Alerts, Backup SMTP & Mobile App <= 3.6.1 - Missing Authorization to Authenticated (Subscriber+) OAuth Token Update","descriptions":[{"lang":"en","value":"The Post SMTP plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.6.1.
