Description OSIDB Bzimport 2026-08-28 19:43:26 UTC
Zipkin through 3.6.1 exposes Spring Boot Actuator endpoints on the tracing API port without authentication, allowing unauthenticated attackers to access sensitive information. Attackers can read environment variables, bean configurations, and storage credentials via actuator endpoints, or modify log levels to suppress logging.
