Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cross-Site Scripting (XSS): Vector (SVG) media components have suffered from recurring XSS vulnerabilities, demanding strong origin-isolation and sandboxing to prevent scripts from executing under the host application domain.
Sandbox Escape: Improper configuration of iframe sandbox properties (specifically combining 'allow-same-origin' with 'allow-scripts') historically permitted complete bypass of isolation boundaries.
Cross-Site Scripting (XSS): PDF previews present an active XSS threat vector if interactive script execution inside the PDF viewing context is not constrained via restrictive HTML5 sandbox rules.
