I'm not sure if this is a plugin or a parser problem. It does not crash but it seems more related to the parser (not giving the proper type to the rule) than actual rule. Sorry if I'm wrong.

• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I have read the FAQ and my problem is not listed.

Repro

Demo repo:
https://github.com/dzek69/bug-typescript-eslint-unsafe-any-getter

• install deps (use yarn for version locks),
• run yarn lint

{
  "rules": {
    "@typescript-eslint/no-unsafe-call": "error",
    "@typescript-eslint/no-unsafe-member-access": "error"
  },
  "parserOptions": {
    "sourceType": "module",
    "project": "./tsconfig.lint.json",
    "ecmaVersion": 9
  }
}

class Item {
    get data() {
        return {
            count: 6,
        }
    }
}

class Test {
    public get stuff() {
        return {
            list: [
                new Item(),
                new Item(),
                new Item(),
            ]
        }
    }

    public get numberStuff(): { list: Item[] } { // manually specifying the type is not helping
        return {
            list: [
                new Item(),
                new Item(),
                new Item(),
            ]
        }
    }
}

const x = new Test();

x.stuff.list.find(a => a.data.count < 3); // problem happens here

tsconfig: https://github.com/dzek69/bug-typescript-eslint-unsafe-any-getter/blob/master/tsconfig.lint.json

Expected Result

No errors should be given. Eslint should be able to get the types information from getters code

Actual Result

Two errors are happening here, both related to accessing data via getters, IDE and TypeScript don't have problems getting correct types here, Eslint does

  33:1   error  Unsafe call of an `any` typed value           @typescript-eslint/no-unsafe-call
  33:24  error  Unsafe member access .data on an `any` value  @typescript-eslint/no-unsafe-member-access
