Description
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to incorrect processing of CSP. 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.
Remediation
Install updates from vendor's website.
