description

Zion Builder through version 3.6.17 is affected by unsafe handling of uploaded SVG files. A user with Author-level access or higher can upload a malicious SVG, potentially causing script execution in the browser of someone who views it.

mitigation

Disable or restrict SVG uploads for untrusted authors and remove or review existing uploaded SVG files. Upgrade to a vendor release that addresses this issue when one is available; the supplied evidence does not name a fixed version.
