CVE-2026-67344: Missing Authorization in ArcadeData arcadedb
ArcadeDB before 26.7.2 fails to enforce the UPDATE_SCHEMA database permission on the ALTER TYPE ... CUSTOM and ALTER TYPE ... BUCKETSELECTIONSTRATEGY SQL operations, which map to setCustomValue and setBucketSelectionStrategy in LocalDocumentType. An authenticated user with only read access (e.g., a read-only API token) can submit these ALTER TYPE statements via the HTTP command endpoint to mutate a type's custom schema metadata and bucket-selection strategy, bypassing the documented updateSchema permission boundary and potentially corrupting schema metadata and record routing.
AI Analysis
Technical Summary
CVE-2026-67344 describes a missing authorization check in ArcadeDB before version 26.7.2. Specifically, the database fails to enforce the UPDATE_SCHEMA permission on ALTER TYPE ... CUSTOM and ALTER TYPE ... BUCKETSELECTIONSTRATEGY SQL statements. These operations correspond to the setCustomValue and setBucketSelectionStrategy methods in LocalDocumentType. An authenticated user with read-only privileges can exploit this flaw by submitting ALTER TYPE commands through the HTTP endpoint, thereby modifying schema metadata and bucket selection strategies without proper authorization. This bypasses the documented permission model and risks schema corruption and improper record routing.
Potential Impact
An attacker with only read access can escalate their privileges to modify critical schema metadata and bucket selection strategies. This unauthorized modification can lead to corruption of the database schema and affect how records are routed internally, potentially impacting database integrity and operation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the HTTP command endpoint to trusted users only and monitor for unauthorized ALTER TYPE commands. Avoid using read-only API tokens in untrusted environments.
