CVE-2026-119188: Forge TLS handshake denial of service

CVE-2026-119188 · Severity: high · CVSS 7.5 · Published 2026-10-29

Forge is a JavaScript library that implements TLS (Transport Layer Security), the encryption protocol used to secure web traffic and other network communications. A flaw in how it processes fragmented TLS handshake messages could allow a remote attacker to crash the connection or the entire hosting process by sending specially crafted records, causing a denial of service.

Technologies: Digital Bazaar Forge, node-forge (npm). Vendors: Digital Bazaar, npm.

Check whether you run Digital Bazaar Forge or node-forge (npm) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • node-forge (npm): upgrade to 1.4.1 or later
    npm install node-forge@1.4.1

Technical details

The vulnerability exists in forge.tls.createConnection() where the library fails to properly validate TLS records that interrupt fragmented handshake messages. When a record of unexpected content type interrupts a fragmented handshake, the code throws an uncaught TypeError instead of gracefully rejecting the input. A remote peer can trigger this exception via network packets, causing the connection to terminate or the process to crash.
