CVE-2023-32502Network attack vector

MIME-type setting changes via missing nonce validation

Published Nov 9, 2023 · Updated Apr 28, 2026

Cross-site request forgery in Pro Mime Types 1.0.7 and earlier allows remote attackers to change allowed MIME types via forged requests. The pmt_settings_section_callback_tab_1() settings handler accepts state-changing submissions without validating a WordPress nonce. Exploitation requires a site administrator to follow an attacker-controlled link or perform an equivalent action, after which MIME-type support can be enabled or disabled.
