CVE-2026-59955
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 raw configuration data when AccessKey or management key authentication is enabled because requests under /configfiles/raw/{appId}/{clusterName}/{namespace} are parsed for authentication as appId raw instead of the actual path appId, causing ConfigService to look up AccessKey secrets for raw before verifying the request signature and potentially continue without signature verification for the target appId. This issue is fixed in version 2.5.2.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
