FKIE_CVE-2026-59954

Vulnerability from fkie_nvd - Published: 2026-07-15 17:16 - Updated: 2026-07-15 18:16
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
Apollo is a reliable configuration management system suitable for microservice configuration management scenarios. Prior to 2.5.2, Apollo ConfigService may allow unauthorized access to configuration data when AccessKey or management key authentication is enabled because ConfigService can accept a non-canonical appId variant during authentication while downstream request handling resolves it to the protected app, including accent variants under accent-insensitive collations or trailing-space variants under PAD SPACE collations on /configs and /configfiles endpoints. This issue is fixed in version 2.5.2.
