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.
