description

JetEngine versions before 3.8.13.1 allow unauthenticated upload of SVG files that are not adequately sanitized or access-restricted. An attacker can cause browser-side script execution for users who open a malicious uploaded SVG.

mitigation

Upgrade Crocoblock JetEngine to version 3.8.13.1 or later. Until upgraded, restrict or disable SVG uploads and limit access to existing uploaded SVG files.

fixed in 3.8.13.1
