SVGO's removeScripts plugin, which is disabled by default, fails to remove all executable scripts from SVG files in certain cases. Specifically, it does not remove namespaced or prefixed <script> elements (e.g., <svg:script>) and matches JavaScript URIs case-sensitively instead of case-insensitively. This can leave executable scripts intact, potentially enabling cross-site scripting (XSS) if untrusted SVGs are processed with this plugin and served to users. SVGO patched these issues in versions 3.3.4 and 4.0.2. Users relying on this plugin for sanitization should upgrade or use dedicated SVG sanitization tools.
