Machine-written summary

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

openssl-encrypt versions before 1.4.0 ship hardcoded default JWT signing secrets in config.py that pass the application's validation checks. An attacker who can read the source code can forge valid JWT tokens for any client_id and gain authenticated access to the keyserver and telemetry APIs. Upgrade to openssl-encrypt 1.4.0, which fixes the issue.
