ArcadeDB Cluster Token Exposure Leading to Privilege Escalation

Publication date: 2026-08-01

Last updated on: 2026-08-01

Assigner: VulnCheck

Description
ArcadeDB versions before 26.7.2 fail to properly redact the cluster token in the GET /api/v1/server endpoint, allowing authenticated users to retrieve the arcadedb.ha.clusterToken value in cleartext. Attackers can use the leaked token with X-ArcadeDB-Cluster-Token and X-ArcadeDB-Forwarded-User headers to impersonate root and execute administrative actions including user creation, database operations, and server shutdown.

Executive Summary

ArcadeDB versions before 26.7.2 expose the cluster token in cleartext through the GET /api/v1/server endpoint. Authenticated users can retrieve the arcadedb.ha.clusterToken value, which attackers can misuse with specific headers to impersonate root and perform administrative actions.

Detection Guidance

Check if the GET /api/v1/server endpoint returns the arcadedb.ha.clusterToken in cleartext. Use curl to query the endpoint: curl -X GET http://<server>:<port>/api/v1/server. If the response includes the cluster token, the system is vulnerable.

Impact Analysis

An attacker with network access could gain administrative privileges, create users, manipulate databases, or shut down the server. This requires authentication but allows full control over the ArcadeDB instance once exploited.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating confidentiality requirements in GDPR and HIPAA. Unauthorized administrative actions may also compromise data integrity and availability.

Mitigation Strategies

Upgrade ArcadeDB to version 26.7.2 or later to fix the token exposure issue. If immediate upgrade is not possible, restrict access to the /api/v1/server endpoint and monitor for unauthorized administrative actions.
