What is CVE-2022-4022?
CVE-2022-4022 is a medium-severity cross-site scripting vulnerability in benbodhi SVG Support, published on 16 Nov 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The SVG Support plugin for WordPress defaults to insecure settings in version 2.5 and 2.5.1. SVG files containing malicious javascript are not sanitized. While version 2.5 adds the ability to sanitize image as they are uploaded, the plugin defaults to disable sanitization and does not restrict SVG upload to only administrators. This allows authenticated attackers, with author-level privileges and higher, to upload malicious SVG files that can be embedded in posts and pages by higher privileged users. Additionally, the embedded JavaScript is also triggered on visiting the image URL, which allows an attacker to execute malicious code in browsers visiting that URL.
