Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Cross-Site Scripting (XSS): Inadequate sanitization of dynamic styles during Server-Side Rendering (SSR) allows attackers to inject closing style tags and escape the style block to execute arbitrary script.

Cross-Site Scripting: A case-sensitive sanitization bypass allowed attackers to inject style blocks using mixed-case style tags, which was addressed by switching to a case-insensitive replacement.
