CVE-2026-18202 (GCVE-0-2026-18202)

Vulnerability from cvelistv5 – Published: 2026-08-19 06:00 – Updated: 2026-08-19 16:10

Title

JetEngine < 3.8.14 - Author+ Stored XSS via SVG Upload

Summary

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.

Severity

6.8 (Medium)
