Stored XSS via missing request nonce
Published Feb 6, 2023 · Updated Apr 8, 2026
Cross-site request forgery in Boris Kuzmanov 0mk Shortener 0.2 and earlier allows remote attackers to store malicious scripts. The zeromk_options_page function accepts zeromk_user and zeromk_apikluc values from forged requests without valid nonce verification, allowing script-bearing settings to be saved. Exploitation requires an administrator to submit the forged request, after which the stored payload executes in an affected administrative context.
