CVE-2026-18202

JetEngine < 3.8.14 - Author+ Stored XSS via SVG Upload

Published Aug 19, 2026 CVSS 3.1 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
The JetEngine WordPress plugin before 3.8.14 adds SVG to the site-wide list of allowed upload types without sanitising the file contents, allowing users with the upload files capability, such as Authors, to upload a file containing malicious JavaScript that executes in the browser of any user who opens it (Stored Cross-Site Scripting). On multisite, this also overrides an upload-type restriction set by the network administrator.
