Recurring patterns

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

Cross-Site Scripting (XSS): The SVG editor backend was vulnerable to XSS through unsafe SVG attribute names and values (such as event handlers and javascript: URIs) during direct editing, necessitating strict attribute-level validation.

Path Traversal: Output slice filenames allowed arbitrary directory navigation via path traversal sequences during image slicing operations, which could overwrite critical system files.

Stored XSS: The frontend SVG sanitizer allowed malicious 'javascript:' links inside 'href' and 'xlink:href' attributes, leading to Stored XSS when rendering SVG elements.
