An improper authentication vulnerability exists in curl 7.33.0 to and
including 7.82.0 which might allow reuse OAUTH2-authenticated connections
without properly making sure that the connection was authenticated with the
same credentials as set for this transfer. This affects SASL-enabled
protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).
