Summary

SVGO (SVG Optimizer) is a Node.js library and CLI for optimizing SVG files. From version 1.0.0 until versions 2.8.3, 3.3.4, and 4.0.2, the removeScripts plugin (removeScriptElement in versions 1-3) can leave executable content in optimized SVGs because it does not remove namespaced or prefixed script elements such as <svg:script> and, in versions 3 and 4, matches JavaScript URIs case sensitively. Applications processing untrusted SVG input with this plugin enabled and serving the result can allow scripts to execute when another user opens the SVG, exposing local storage or cookies. Fixed in versions 2.8.3, 3.3.4, and 4.0.2.

Risk Assessment

Users opening optimized SVG files may be exposed to malicious script execution, potentially leading to data theft or session hijacking.

Recommendation

Upgrade SVGO to version 2.8.3, 3.3.4, or 4.0.2 or later, and avoid processing untrusted SVG files without proper safeguards.

Original NVD description (English source)

SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.3, 3.3.4, and 4.0.2, the removeScripts plugin, named removeScriptElement in versions 1 through 3, can leave executable content in optimized SVGs because it does not remove namespaced or prefixed script elements such as <svg:script> and, in versions 3 and 4, matches JavaScript URIs case sensitively. Applications that process untrusted SVG input with this plugin enabled and serve the result can allow scripts to execute when another user opens the SVG, exposing local storage or cookies. This issue is fixed in versions 2.8.3, 3.3.4, and 4.0.2.
