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 a hardcoded default secret key in the standalone telemetry server configuration, which is used for API key hashing. An attacker who knows this default value can predict or forge API key hashes and gain access to telemetry API authentication. Upgrade to openssl-encrypt 1.4.0 or later.
