CVE-2024-39895Public exploitNetwork attack vector

Authenticated service interruption via unlimited GraphQL query parsing

Published Jul 8, 2024 · Updated Aug 2, 2024

Uncontrolled resource consumption in Directus before 10.12.0 allows remote authenticated users to interrupt service via GraphQL queries. The /graphql middleware passed attacker-controlled queries to the GraphQL parser without a token limit, allowing duplicated fields to trigger redundant work. Low-privileged API access is required; a large request leaves the service unresponsive for minutes, and repeated requests sustain the interruption.
