CVE-2023-22461
January 04, 2023
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
