Description
As a security precaution, password caching for email Internet protocols such as POP3 or IMAP may lead to password discovery and eventually to data loss. An attacker that is able to access the users' profile may be able to acquire these cached passwords; they could then use this information to compromise the users' email accounts and other systems that use the same credentials.
