Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

KubePi versions before 1.6.3 (affected <1.6.3) use a hardcoded JWT signing key, so the same key is used across all installations. An attacker can forge JWT tokens and take over the administrator account without logging in. Upgrade to KubePi 1.6.3, which fixes the issue.
