CVE-2026-59955: CWE-20: Improper Input Validation in apolloconfig apollo
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.
AI Analysis
Technical Summary
Apollo ConfigService's raw config file endpoint (/configfiles/raw/{appId}/{clusterName}/{namespace}) improperly parses the appId as "raw" instead of the actual appId in the request path. This leads to the service looking up AccessKey secrets for an app literally named "raw". If no such AccessKey exists, the service treats the request as having no secrets and bypasses signature verification, allowing unauthorized access to raw configuration data despite AccessKey authentication being enabled. This vulnerability is tracked as CVE-2026-59955 and fixed in Apollo 2.5.2.
Potential Impact
An unauthenticated remote attacker can bypass AccessKey authentication and read raw configuration data from the affected Apollo ConfigService endpoint. This exposure of sensitive configuration information can lead to information disclosure without requiring any privileges or user interaction.
Mitigation Recommendations
A fix is available in Apollo version 2.5.2. Users should upgrade to version 2.5.2 or later to remediate this vulnerability. No other mitigations are indicated by the vendor advisory.
