CVE-2023-25570: Apollo has potential access control security issue in eureka

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.8% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2023-02-20 · updated 2026-06-17
• Weakness: CWE-306

Description

Apollo is a configuration management system. Prior to version 2.1.0, there are potential security issues if users expose apollo-configservice to the internet, which is not recommended. This is because there is no authentication feature enabled for the built-in eureka service. Malicious hackers may access eureka directly to mock apollo-configservice and apollo-adminservice. Login authentication for eureka was added in version 2.1.0. As a workaround, avoid exposing apollo-configservice to the internet.

Affected products

• apolloconfig apollo: before 2.1.0 — fixed in 2.1.0

How to fix

Upgrade to a fixed version: apolloconfig apollo 2.1.0. Check the vendor advisory for mitigations.
