CVE-2026-33891

CVE-2026-33891 affects Forge/node-forge prior to 1.4.0, where BigInteger.modInverse() can enter an infinite loop when given zero, causing a DoS with 100% CPU. The issue is resolved in 1.4.0. Related OSV entries confirm patches in downstream packages (e.g., Root’s @rootio/node-forge) with multiple...
