CVE-2026-54155

node-opcua (NPM, versions ≤ 2.165.0) contains a missing nonce verification in the UserNameIdentityToken authentication handler (packages/node-opcua-server/source/opcua_server.ts). After RSA-OAEP decryption of the password blob, the server never checks that trailing bytes match session.nonce. This...

CVE-2026-54155 node-opcua: Missing nonce verification in UserNameIdentityToken authentication

node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to 2.166.0, the UserNameIdentityToken authentication handler in packages/node-opcua-server/source/opcuaserver.ts decrypts an RSA-OAEP password blob but does not verify that the trailing bytes match the current session...
