## Technical details

A cross-site scripting (XSS) vulnerability exists in the StaticResourceServer.validateSvgContent function due to insufficient validation of SVG content, allowing attackers to bypass security checks through tab/entity-based URL manipulation. The vulnerability affects the SVG Handler component in DataEase and can be exploited remotely without authentication. The fix replaces blacklist-based validation with namespace-aware allowlists, restricts references to document-local fragments, and applies restrictive Content Security Policy headers.
