CVE-2026-54076: CWE-862: Missing Authorization in ArcadeData arcadedb
ArcadeDB is a Multi-Model DBMS. Prior to 26.6.1, the fix for CVE-2026-44221 added an UPDATE_SCHEMA authorization check only to LocalDocumentType.createProperty, while the remaining public schema mutators in engine/src/main/java/com/arcadedb/schema/LocalDocumentType.java and engine/src/main/java/com/arcadedb/schema/LocalProperty.java remained unchecked. An authenticated identity, including a read-only API token without UPDATE_SCHEMA permission, can use DROP PROPERTY, ALTER TYPE, or ALTER PROPERTY through the database command/query HTTP endpoints to rename types, change inheritance, alter aliases or buckets, drop properties, and change property constraints. The issue does not directly disclose or write record data, but unauthorized schema mutation can corrupt the meaning of stored records and breach the documented permission model. This issue is fixed in version 26.6.1.
AI Analysis
Technical Summary
ArcadeDB versions before 26.6.1 contain a missing authorization vulnerability (CWE-862) where the fix for a previous issue (CVE-2026-44221) only added UPDATE_SCHEMA checks to LocalDocumentType.createProperty. Other schema mutation methods in LocalDocumentType.java and LocalProperty.java remained unchecked, allowing authenticated users without UPDATE_SCHEMA permission to perform unauthorized schema mutations such as DROP PROPERTY, ALTER TYPE, and ALTER PROPERTY via HTTP database command/query endpoints. These unauthorized schema changes can corrupt the meaning of stored records and violate the documented permission model. The vulnerability has a CVSS 3.1 score of 8.1 (high severity) and was addressed in ArcadeDB version 26.6.1.
Potential Impact
Unauthorized authenticated users can mutate the database schema without proper authorization, potentially corrupting the meaning and integrity of stored records and violating the intended permission model. Although record data is not directly disclosed or modified, schema corruption can lead to significant data integrity and security issues.
Mitigation Recommendations
Upgrade to ArcadeDB version 26.6.1 or later, where this missing authorization issue has been fixed. No other mitigations are indicated by the vendor advisory.
