Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apollo ConfigService versions 2.0.1 and earlier may let an unauthenticated remote attacker read configuration data from the /configs and /configfiles endpoints when AccessKey authentication is enabled and the database collation treats a non-canonical appId as equivalent to the real one. Upgrade to Apollo 2.5.2 or later.
