{"id":"CVE-2026-75966","state":"PUBLISHED","title":"Podlove Podcast Publisher <= 4.5.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter","description":"The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The contributor comment is stored in a plugin-managed custom table, bypassing WordPress core's wp_kses_post filter, and the save_post hook fires without a nonce check, meaning any user who can edit posts can exploit this without further preconditions.","publishedAt":"2026-09-09T03:28:49.209Z","updatedAt":"2026-09-09T16:03:16.188Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["eteubert Podlove Podcast Publisher"],"affected":[{"vendor":"eteubert","product":"Podlove Podcast Publisher","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.5.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/fc9253bc-feee-422f-aafb-1630f2d1ad2e?source=cve","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.4/lib/modules/contributors/contributors.php#L490","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.5/lib/modules/contributors/templates/contributor-table.twig#L59","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.5/lib/modules/contributors/contributors.php#L490","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.5/lib/modules/contributors/contributors.php#L25","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.5/lib/template/twig_filter.php#L139","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.4/lib/modules/contributors/templates/contributor-table.twig#L59","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.4/lib/modules/contributors/contributors.php#L25","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.4/lib/template/twig_filter.php#L139","https://plugins.trac.wordpress.org/changeset?reponame=&old=3671120%40podlove-podcasting-plugin-for-wordpress&new=3671120%40podlove-podcasting-plugin-for-wordpress"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/75xxx/CVE-2026-75966.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-75966","state":"PUBLISHED","datePublished":"2026-09-09T03:28:49.209Z","dateUpdated":"2026-09-09T16:03:16.188Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-18T17:03:27.614Z"},"containers":{"cna":{"title":"Podlove Podcast Publisher <= 4.5.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter","descriptions":[{"lang":"en","value":"The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping.
