CVE-2026-76223: Missing Authorization in ArcadeData arcadedb
ArcadeDB (com.arcadedb) versions 26.7.3 and earlier fail to enforce the UPDATE_SCHEMA permission check when a DEFINE FUNCTION statement targets an already-existing function library. A user with only database access can add or overwrite SQL or Cypher functions in an existing library and persist the change, enabling tampering with admin-defined function logic. The issue is fixed in 26.8.1. (JavaScript functions still trigger the UPDATE_SECURITY check and are not affected.)
AI Analysis
Technical Summary
ArcadeDB (com.arcadedb) versions 26.7.3 and earlier do not enforce the UPDATE_SCHEMA permission check when a DEFINE FUNCTION statement modifies an already-existing function library. This missing authorization allows users with only database access privileges to add or overwrite SQL or Cypher functions within existing libraries and persist those changes, enabling unauthorized tampering with administrative function logic. JavaScript functions remain protected by the UPDATE_SECURITY check and are not impacted by this vulnerability. The vulnerability is resolved in version 26.8.1.
Potential Impact
An attacker with database access but without UPDATE_SCHEMA permission can modify or add SQL or Cypher functions in existing function libraries, potentially altering administrative logic and affecting database behavior or security. This could lead to unauthorized changes in database operations. JavaScript functions are unaffected, limiting the scope of impact.
Mitigation Recommendations
Upgrade to ArcadeDB version 26.8.1 or later, where the missing UPDATE_SCHEMA permission check has been implemented to prevent unauthorized modification of existing function libraries. Until the upgrade, restrict database access to trusted users only.
