{"id":"CVE-2026-1043","state":"PUBLISHED","title":"PostmarkApp Email Integrator <= 2.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via Plugin Settings","description":"The PostmarkApp Email Integrator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in versions up to, and including, 2.4. This is due to insufficient input sanitization and output escaping on the pma_api_key and pma_sender_address parameters. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the settings page.","publishedAt":"2026-02-19T04:36:17.315Z","updatedAt":"2026-04-08T17:03:37.150Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["gagan0123 PostmarkApp Email Integrator"],"affected":[{"vendor":"gagan0123","product":"PostmarkApp Email Integrator","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/80b03e81-6660-483a-9150-e6075b7bffbd?source=cve","https://plugins.trac.wordpress.org/browser/postmarkapp-email-integrator/trunk/postmarkapp.php#L149","https://plugins.trac.wordpress.org/browser/postmarkapp-email-integrator/tags/2.4/postmarkapp.php#L149","https://plugins.trac.wordpress.org/browser/postmarkapp-email-integrator/trunk/postmarkapp.php#L153","https://plugins.trac.wordpress.org/browser/postmarkapp-email-integrator/trunk/postmarkapp.php#L68"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1043.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1043","state":"PUBLISHED","datePublished":"2026-02-19T04:36:17.315Z","dateUpdated":"2026-04-08T17:03:37.150Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-16T15:53:22.420Z"},"containers":{"cna":{"title":"PostmarkApp Email Integrator <= 2.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via Plugin Settings","descriptions":[{"lang":"en","value":"The PostmarkApp Email Integrator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in versions up to, and including, 2.4.
