What is CVE-2021-24386?
CVE-2021-24386 is a medium-severity cross-site scripting vulnerability in KubiQ WP SVG images, published on 6 Jul 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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. The description of the plugin has also been updated with a security warning as upload of such content is intended.
