CVE-2026-82265
Description
A flaw was found in Zipkin. Unauthenticated attackers can exploit exposed Spring Boot Actuator endpoints on the tracing API port to access sensitive information. This allows them to read environment variables, bean configurations, and storage credentials. Additionally, attackers can modify log levels, potentially suppressing important logging information.
Statement
An unauthorized access flaw was found in Zipkin. The application exposes Spring Boot Actuator management endpoints directly on the tracing API network port without enforcing authentication or access controls. An unauthenticated remote attacker can exploit these endpoints to extract sensitive runtime configuration details, including environment variables, bean definitions, and storage credentials, or modify log levels to suppress security auditing.
Mitigation
Restrict access to Spring Boot Actuator endpoints by configuring explicit web security authentication rules, or isolate the management port from public exposure by setting `management.server.port` to a dedicated internal network interface.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control,Other
Technical Impact: Gain Privileges or Assume Identity; Varies by Context
Exposing critical functionality essentially provides an attacker with the privilege level of that functionality. The consequences will depend on the associated functionality, but they can range from reading or modifying sensitive data, accessing administrative or other privileged functionality, or possibly even executing arbitrary code.
