{"id":"CVE-2025-21624","summary":"ClipBucket V5 Playlist Cover File Upload to Remote Code Execution","details":"ClipBucket V5 provides open source video hosting with PHP. Prior to 5.5.1 - 239, a file upload vulnerability exists in the Manage Playlist functionality of the application, specifically surrounding the uploading of playlist cover images. Without proper checks, an attacker can upload a PHP script file instead of an image file, thus allowing a webshell or other malicious files to be stored and executed on the server. This attack vector exists in both the admin area and low-level user area. This vulnerability is fixed in 5.5.1 - 239.","aliases":["GHSA-98vm-2xqm-xrcc"],"modified":"2026-04-02T12:35:10.292441Z","published":"2025-01-07T15:46:11.169Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21624.json","cwe_ids":["CWE-434"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21624.json"},{"type":"ADVISORY","url":"https://github.com/MacWarrior/clipbucket-v5/security/advisories/GHSA-98vm-2xqm-xrcc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-21624"},{"type":"FIX","url":"https://github.com/MacWarrior/clipbucket-v5/commit/893bfb0f1236c4a59b5e2843ab8d27a1e491b12b"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/macwarrior/clipbucket-v5","events":[{"introduced":"0"},{"fixed":"893bfb0f1236c4a59b5e2843ab8d27a1e491b12b"}]}],"versions":["5.3","5.3.1","5.4.0","5.4.1","5.5.0"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"5.3"},{"fixed":"5.5.1-239"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-21624.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
