AWS clean-rooms high security documentation change

Service: clean-rooms · 2025-05-22 · Security-related high

File: clean-rooms/latest/sql-reference/s_SHA2.md

Summary

Replaced MURMUR3_32_HASH with xxhash64 in supported hash function options

Security assessment

Replaced a non-cryptographic hash (MURMUR3) with another non-cryptographic hash (xxhash64) in SHA2 context. SHA2 is a cryptographic hash family, so this change might mislead users into using weaker hashes where cryptographic strength is expected, creating potential security risks.
