CVE-2026-30946Network attack vector

Service interruption via unbounded REST and GraphQL queries

Published Mar 10, 2026 · Updated Mar 10, 2026

Resource exhaustion in Parse Server before 8.6.15 and 9.0.0 through 9.5.2-alpha.1 allows remote attackers to interrupt service. REST subquery and include nesting and GraphQL selection depth and field count are processed without limits, consuming CPU, memory, and database connections. Exposure of either API is sufficient; crafted unauthenticated queries can exhaust the server resources available to legitimate requests.
