High impact if exploited, but EPSS currently rates exploitation as unlikely (0.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
