What is CVE-2026-74893?

The OpenSSL Encrypt application prior to version 1.4.0 contains hardcoded default JWT signing secrets within its configuration file (config.py). This flaw allows attackers with access to the source code to create forged JWT tokens, enabling unauthorized access to keyserver and telemetry APIs by validating requests impersonating any client_id. Proper security practices and version upgrades are crucial to mitigate this risk.

Affected Version(s)

openssl_encrypt 0 < 1.4.0

openssl_encrypt 1.4.0
