CVE-2026-33729: Openfga Cache Key Injective Serializationcve-2026-33729-openfga-cache-key-injective-serialization
Cache key serialization for a protobuf Struct must prefix the number of fields (e.g. via strconv.Itoa(len(keys))) and sanitize Unicode control characters in string values. Without a length prefix, a single-key value containing the literal field delimiter (e.g. ",'b:'y") serializes identically to a structurally different two-key Struct, producing the same cac
