A fix is available — apply it.

ArcadeDB before 26.8.1 contains a denial of service vulnerability in the Cypher range() function that allows authenticated users to exhaust server heap memory. Attackers can submit oversized range() expressions with large bounds to trigger OutOfMemoryError and cause temporary service degradation or unavailability.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
