Prior to 15.32.3, GraphQL\\Language\\Parser performs recursive descent without a recursion limit in parseSelectionSet, parseValueLiteral, and parseTypeReference. A remote attacker can submit deeply nested selection sets, object or list values, or list types that exhaust the PHP process stack during pre-validation parsing, before query validation and complexity controls run. The resulting SIGSEGV can terminate PHP-FPM workers or long-running Swoole, RoadRunner, ReactPHP, or CLI processes and cannot be caught by application-level exception handling. This issue is fixed in version 15.32.3.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":45.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
