Summary
An issue in HTMLy version 3.1.1 lets a remote attacker escalate privileges through the get_feed function in the admin.php component. The flaw is improper privilege management (CWE-269), which lets a request gain rights the account should not have. An unauthenticated remote attacker can exploit it without user interaction, and it can fully compromise confidentiality, integrity and availability.
