CVE-2026-82265
Zipkin through 3.6.1 exposes Spring Boot Actuator endpoints on the tracing API port without authentication, allowing unauthenticated attackers to access sensitive information.
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
Description
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.
