What is CVE-2025-14579?

The Quiz Maker plugin for WordPress prior to version 6.7.0.89 contains a vulnerability that fails to adequately sanitize and escape certain settings.

Even in configurations where the 'unfiltered_html' capability is disabled—such as on multisite setups—this vulnerability poses a significant threat by enabling malicious scripts to be injected and executed. It is crucial for users of this plugin to update to the latest version to mitigate the associated risks.
