This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
