CVE-2024-50507Public exploitNetwork attack vector

Unauthenticated object injection via untrusted deserialization

Published Oct 30, 2024 · Updated May 11, 2026

PHP object injection in Daschmi DS.DownloadList 1.3 and earlier allows remote attackers to inject objects through untrusted serialized input. The unauthenticated dsdl AJAX action accepts a base64-encoded atts value that is decoded and deserialized without blocking object creation. No user interaction is required, but file deletion, data retrieval, or code execution depends on a usable POP chain from another installed plugin or theme.
