AI-suggested
Official patches are available in SVGO versions 2.8.1, 3.3.3, and 4.0.1. Users should upgrade to these or later versions to remediate the vulnerability. The Red Hat advisory notes that no alternative mitigations meet their criteria for ease of use and applicability, so upgrading is the recommended action.
Description
SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 2.1.0 to before version 2.8.1, from version 3.0.0 to before version 3.3.3, and before version 4.0.1, SVGO accepts XML with custom entities, without guards against entity expansion or recursion. This can result in a small XML file (811 bytes) stalling the application and even crashing the Node.js process with JavaScript heap out of memory. This issue has been patched in versions 2.8.1, 3.3.3, and 4.0.1.
