What is CVE-2026-29074?

The SVGO library, crucial for optimizing SVG files, has a vulnerability that allows the processing of XML containing custom entities, leading to potential application stalls or crashes. Specifically, this issue can occur when an attacker supplies a deceptively small XML file, triggering the Node.js process to exhaust memory resources. This vulnerability persists in multiple versions prior to 2.8.1, 3.3.3, and 4.0.1, making it imperative for users to upgrade to the latest versions to prevent service disruptions and enhance security.
