ArcadeDB before 26.8.1 Unauthorized Function Deletion via DELETE FUNCTION

Assigner: VulnCheck
Reserved: 18.08.2026 Published: 18.08.2026 Updated: 18.08.2026

ArcadeDB before 26.8.1 (affected versions <= 26.7.3) contains a missing authorization vulnerability in the DELETE FUNCTION SQL statement. DeleteFunctionStatement.executeSimple unregisters and persists deletion of a server-side function without any checkPermissionsOnDatabase (UPDATE_SCHEMA) check. Any user with database access can execute DELETE FUNCTION via the command API (POST /api/v1/command/{db}) to permanently remove any registered server-side function, including security-relevant logic, impacting integrity and availability.
