CVE-2026-33891
EUVD-2026-1683327.03.2026, 21:17
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.

Common Weakness Enumeration
- CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')The program contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
- CWE-606 - Unchecked Input for Loop ConditionThe product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
