CVE-2026-47784 is an observable timing discrepancy in Memcached versions before 1.6.42 during SASL password-database authentication. The sasl_server_userdb_checkpass password-verification logic uses memcmp, whose execution time can vary according to the extent of matching password data. An unauthenticated remote party may measure authentication response times over repeated attempts to infer password bytes incrementally.
