Process crash via recursive malformed-schema parsing
Published Aug 1, 2022 · Updated Aug 25, 2026
Uncontrolled recursion in graphql-go before 0.8.1 allows remote attackers to crash a consuming Go process with malformed schema input. The parseTypeSystemDefinition function treats an unrecognized leading name as another type-system definition without advancing the token, so String r repeatedly re-enters the same function until stack overflow. The process must pass attacker-controlled schema text to Parse; the demonstrated result is a Go runtime stack-overflow crash, not data access or code execution.
