CVE-2019-25740Public exploitNetwork attack vector

Authenticated file deletion via unchecked custom-field path

Published Jun 4, 2026 · Updated Jun 4, 2026

Path traversal in JoomSky JS Jobs 1.2.6 allows remote authenticated users to delete arbitrary files through a crafted job submission. The storeJob function accepts an unchecked custom-file field value and passes it to uploadOrDeleteFileCustom, which appends it to a server path and calls unlink. Exploitation requires a valid session and an administrator-created file-type custom field; deletion is limited to files accessible to the web server process.
