chore: Enable CSP by default #24262

kgabryje · 2023-06-01T11:49:13Z

SUMMARY

This PR enables TALISMAN_ENABLED by default and provides a default content security policy config.
Please keep in mind that this is a breaking change. If your Superset deployment loads additional scripts, loads images from external domains, performs HTTP requests to external domains, you need to adjust the default CSP config by adding external origins to appropriate CSP directives and/or mark the scripts with nonce as described in the updated docs.

superset-frontend/packages/superset-ui-core/src/models/ExtensibleFunction.ts

  constructor(fn: Function) {
-    super();


Calling new Function() breaks the CSP rule that disallows using eval in scripts.
Extending Function is a nice hack that let's us make a class instance (in most cases it's a formatter) callable - for example instead of calling formatter.format(value) we call formatter(value). Removing super() does not break that behaviour while also letting us avoid calling Function constructor.

Two things re: docs changes:

Typo: "Superset needs both style-src unsafe-inline CSP directive in order to operate." should be "Superset needs the ..."
Changing force_https to now default to False seems good to me. But it means that this section on the Security page "Other Talisman security considerations" needs to be updated. For instance right now there's text talking about how to override the default value of force_https = True.

Well spotted @sfirke, thank you!

superset/config.py

+        "script-src": ["'self'", "'strict-dynamic'"],
+    },
+    "content_security_policy_nonce_in": ["script-src"],
+    "force_https": False,


@kgabryje curious why this force_https change?

I wanted to limit the scope of the changes in this PR just to CSP - and force_https was disabled by default so far (since Talisman was disabled by default)

I agree with keeping this disabled by default - I would wager that by far the majority of prod Superset deployments terminate SSL/TLS on the LB.

LGTM, i just left one question. Thanks @kgabryje!

Looks great! One honest question and one potential improvement idea, LMKWYT?

+# React requires `eval` to work correctly in dev mode

+    "content_security_policy": {
+        "default-src": ["'self'"],
+        "img-src": ["'self'", "data:"],

+    },

shouldn't we set force_https: False here, too? AFAIK it defaults to True, right?

Yup nice catch!

superset/initialization/__init__.py

+        talisman_config = (
+            self.config["TALISMAN_DEV_CONFIG"]
+            if self.superset_app.debug
+            else self.config["TALISMAN_CONFIG"]
+        )


I'm wondering if it's a good idea to have separate dev and non-dev configs. Should these maybe be TALISMAN_DEFAULT_DEV_CONFIG and TALISMAN_DEFAULT_PROD_CONFIG, and only if TALISMAN_CONFIG is undefined would we fall back to the default. Thoughts?

We must have "unsafe-eval" in dev mode - React and Webpack use it and there's no way around it
