SpiderMonkey is the code-name for Mozilla Firefox's C++ implementation of JavaScript. It is intended to be embedded in other applications that provide host environments for JavaScript.
Security Fix(es):
A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy connect-src header to be ignored. This could lead to connections to restricted origins from inside WebWorkers. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.(CVE-2023-23602)
