{"id":"CVE-2026-16099","state":"PUBLISHED","title":"Podlove Podcast Publisher <= 4.5.3 - Authenticated (Contributor+) PHP Object Injection to Arbitrary File Deletion via 'unfurl_data' Parameter","description":"The Podlove Podcast Publisher plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the create_link_item function in all versions up to, and including, 4.5.3. This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). A viable POP chain exists within the plugin itself via Podlove\\ImageCache\\GenerationGuard, whose __destruct() method invokes wp_delete_file() with an attacker-controlled file path populated through unserialization.","publishedAt":"2026-08-16T04:24:51.333Z","updatedAt":"2026-08-17T15:42:32.010Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["eteubert Podlove Podcast Publisher"],"affected":[{"vendor":"eteubert","product":"Podlove Podcast Publisher","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.5.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3aa6fd71-337f-4998-a15d-650aa4f6142c?source=cve","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L585","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/model/base.php#L552","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/image_cache/generation_guard.php#L19","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/image_cache/generation_guard.php#L57","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L538","https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L630","https://plugins.trac.wordpress.org/changeset?reponame=&old=3648110%40podlove-podcasting-plugin-for-wordpress&new=3648110%40podlove-podcasting-plugin-for-wordpress"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/16xxx/CVE-2026-16099.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-16099","state":"PUBLISHED","datePublished":"2026-08-16T04:24:51.333Z","dateUpdated":"2026-08-17T15:42:32.010Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-17T14:21:10.469Z"},"containers":{"cna":{"title":"Podlove Podcast Publisher <= 4.5.3 - Authenticated (Contributor+) PHP Object Injection to Arbitrary File Deletion via 'unfurl_data' Parameter","descriptions":[{"lang":"en","value":"The Podlove Podcast Publisher plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the create_link_item function in all versions up to, and including, 4.5.3.
