CVE-2026-75839: Exposure of Sensitive Information to an Unauthorized Actor in ArcadeData arcadedb
ArcadeDB versions up to 26.7.3 have an insecure direct object reference (IDOR) vulnerability in the Raft cluster-info endpoints that allows authenticated users to access sensitive cluster metadata without proper authorization. This affects high-availability clusters with the ha-raft module enabled. The vulnerability enables enumeration of the full server database registry and retrieval of metadata such as database names, last transaction IDs, bootstrap fingerprints, and cluster topology. The issue is fixed in version 26.8.1.
AI Analysis
Technical Summary
ArcadeDB (com.arcadedb:arcadedb-server) versions <= 26.7.3 contain an IDOR vulnerability in the Raft cluster-info endpoints (GetClusterHandler and PostBootstrapStateHandler). These endpoints authenticate users but do not enforce authorization, allowing any authenticated user, even those with limited or no database access, to enumerate the entire database registry and retrieve sensitive metadata about all databases in the cluster. This vulnerability affects ArcadeDB HA clusters where arcadedb.ha.enabled is set and the ha-raft module is loaded. The vulnerability is resolved in version 26.8.1.
Potential Impact
An authenticated user can access sensitive cluster metadata across all databases in an ArcadeDB HA cluster, including database names, last transaction IDs, bootstrap fingerprints, and cluster topology information. This results in cross-database information disclosure, potentially aiding further attacks or reconnaissance. There is no indication of privilege escalation or data modification from this vulnerability.
Mitigation Recommendations
Upgrade ArcadeDB to version 26.8.1 or later, where this vulnerability is fixed. No other official remediation or temporary fix is indicated. Until patched, restrict access to authenticated users and consider disabling the ha-raft module if not required.
