Technical details

The Premium Packages plugin for WordPress is vulnerable to an authentication bypass due to improper validation in the download() function, which is hooked to the unauthenticated 'wp' action. The function processes the attacker-controlled 'wpdmppdl' parameter using only base64_decode() and json_decode() without any HMAC, cryptographic signature, or nonce verification. Furthermore, a domain check intended to secure the process is trivially bypassed because both sides of the comparison are derived from attacker-supplied values. An unauthenticated attacker can exploit this to issue WordPress authentication cookies for any non-administrator user (such as subscribers, authors, or shop managers) who owns an order. The vulnerability is present in all versions up to and including 7.0.4.
