Descriptions

A privilege escalation vulnerability exists in Node.js <19.6.1, <18.14.1, <16.19.1 and <14.21.3 that made it possible to bypass the experimental Permissions (https://nodejs.org/api/permissions.html) feature in Node.js and access non authorized modules by using process.mainModule.require(). This only affects users who had enabled the experimental permissions option with --experimental-policy.

This update for nodejs12 fixes the following issues. Fixed permissions policies bypass via process.mainModule. Fixed permissions policies bypass via Module._load. Fixed permissions policies impersonation using module.constructor.createRequire. Fixed permissions policies bypass via process.binding. Fixed mainModule.proto bypass. Fixed missing DiffieHellman key generation. Fixed HTTP Request Smuggling via Empty headers separated by CR.
