Last modified
CVE-2026-30946 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior 9.5.2-alpha.2 and 8.6.15, an unauthenticated attacker can exhaust Parse Server resources (CPU, memory, database connections) through crafted queries that exploit the lack of complexity limits in the REST and GraphQL APIs. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
