CVE-2021-24386
Last modified
CVE-2021-24386 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. The WP SVG images WordPress plugin before 3.4 did not sanitise the SVG files uploaded, which could allow low privilege users such as author+ to upload a malicious SVG and then perform XSS attacks by inducing another user to access the file directly. In v3.4, the plugin restricted such upload to editors and admin, with an option to also allow author to do so. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
