Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

The sanitize-svg package, a small SVG sanitizer to prevent cross-site scripting attacks, uses a deny-list-pattern to sanitize SVGs to prevent XSS. In doing so, literal <script>-tags and on-event handlers were detected in versions prior to 0.4.0. As a result, downstream software that relies on sanitize-svg and expects resulting SVGs to be safe, may be vulnerable to cross-site scripting. This vulnerability was addressed in v0.4.0. There are no known workarounds
