To report a genuine* security vulnerability with angular-eslint, please use the Tidelift security contact. Tidelift will coordinate the fix and disclosure.
*Not all flagged vulnerabilities are valid and context is important. angular-eslint is a development time only toolset, it is never deployed to a server and never takes user input other than your own.
