CVE-2026-33891: Digitalbazaar Forge

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, a Denial of Service (DoS) vulnerability exists in the node-forge library due to an infinite loop in the BigInteger.modInverse() function (inherited from the bundled jsbn library). When modInverse() is called with a zero value as input, the internal Extended Euclidean Algorithm enters an unreachable exit condition, causing the process to hang indefinitely and consume 100% CPU. Version 1.4.0 patches the issue.

Affected products

• Digitalbazaar Forge: up to and including 1.3.3
