Technical details
The Ickle query parser in Infinispan uses recursive parsing that can be exhausted by queries containing deeply nested predicates, leading to a StackOverflowError that crashes the thread. An authenticated attacker with BULK_READ permission can craft and submit such a malicious query to trigger a denial of service. The vulnerability requires authentication and specific permissions, limiting exposure.
