What is CVE-2018-9846?

In versions 1.2.0 to 1.3.5 of Roundcube Webmail, the archive plugin presents a security risk due to unsanitized user-controlled parameters. Specifically, the '_uid' parameter in the archive.php script allows for the execution of IMAP commands after a '%0d%0a' sequence, potentially leading to an IMAP injection attack. Although later versions implement protective measures through a Same Origin Policy, earlier versions remain vulnerable, emphasizing the need for immediate security assessments and updates.
