MITRE has issued two CVE's now:

CVE-2026-47783
--------------
In memcached before 1.6.42, username data for SASL password database
authentication has a timing side channel because a loop exits as soon
as a valid username is found by sasl_server_userdb_checkpass.

CVE-2026-47784
--------------
In memcached before 1.6.42, password data for SASL password database
authentication has a timing side channel because memcmp is used by
sasl_server_userdb_checkpass.
