CVE-2026-33896
March 27, 2026
Forge (also called "node-forge") is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, "pki.verifyCertificateChain()" does not enforce RFC 5280 basicConstraints requirements when an intermediate certificate lacks both the "basicConstraints" and "keyUsage" extensions. This allows any leaf certificate (without these extensions) to act as a CA and sign other certificates, which node-forge will accept as valid. Version 1.4.0 patches the issue.
