CVE-2023-27524Apache Superset — the signing key nobody changed

Apache Superset up to 2.0.1 ships with a default session signing key, so an installation that kept it lets an attacker mint a session of their own and arrive as any user. Exploit code is public and installations are found this way routinely.

YOUR NEXT MOVE

Set a unique random signing key in the Superset configuration and restart, then upgrade past 2.0.1. Sessions issued under the default key should be treated as forged.
