CVE-2022-33994 is a low-severity cross-site scripting vulnerability in n/a, published on 30 Jul 2022. 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 Gutenberg plugin through 13.7.3 for WordPress allows stored XSS by the Contributor role via an SVG document to the "Insert from URL" feature. NOTE: the XSS payload does not execute in the context of the WordPress instance's domain; however, analogous attempts by low-privileged users to reference SVG documents are blocked by some similar products, and this behavioral difference might have security relevance to some WordPress site administrators.
