{"id":"CVE-2026-16099","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-16099","summary":"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…","details":"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.","published":"2026-08-16T05:16:47.780","modified":"2026-08-16T05:16:47.780","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/image_cache/generation_guard.php#L19"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/image_cache/generation_guard.php#L57"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/model/base.php#L552"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L538"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L585"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/podlove-podcasting-plugin-for-wordpress/tags/4.5.3/lib/modules/shownotes/rest_api.php#L630"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3648110%40podlove-podcasting-plugin-for-wordpress&new=3648110%40podlove-podcasting-plugin-for-wordpress"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3aa6fd71-337f-4998-a15d-650aa4f6142c?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T05:16:47.780"}}
