CVE-2021-24763
Last modified
CVE-2021-24763 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. The Perfect Survey WordPress plugin before 1.5.2 does not have proper authorisation nor CSRF checks in the save_global_setting AJAX action, allowing unauthenticated users to edit surveys and modify settings. Given the lack of sanitisation and escaping in the settings, this could also lead to a Stored Cross-Site Scripting issue which will be executed in the context of a user viewing any survey. EPSS estimates a 0.64% chance of exploitation in the next 30 days.
