Could you please create a repro repo for this?
I am unable to repro this against master.

I suspect that there is an issue with your config.

@bradzacher Please see: https://github.com/mf-pherlihy/typescript-eslint-no-unsafe-member-access

> eslint src/test.d.ts

/src/test.d.ts
  2:33  error  Unsafe member access .EventEmitter on an any value  @typescript-eslint/no-unsafe-member-access

✖ 1 problem (1 error, 0 warnings)

interesting. It looks like it's an error due to v13.11.1 of @types/node.
I can't repro it against master, because we have 12.12.7 installed, which is working fine.

I'm not sure what is happening.

doing a pseudo-bisect shows that this is broken from v13.1.0 onwards of @types/node, with v12.12.35 (the latest v12 release at the time) working fine.

I have a repro without any of our packages, so I'm not sure what the problem is. I'll need to keep looking

Looks like you stumbled upon a bug in typescript!

microsoft/TypeScript#37901

I can still reproduce this with

• eslint 7.12.1
• @typescript-eslint/eslint-plugin 4.6.0
• typescript 4.0.5

the linked issue is supposedly fixed since typescript 4.0.1

namespace A {
	export interface B {}
}

export interface C extends A.B {} // Unsafe member access .B on an any value. eslint(@typescript-eslint/no-unsafe-member-access)

that bug is unrelated to this bug - please file a new issue.
that bug is related to the parser.

This bug is fixed in TS 4.0.1+
