CVSS 3.0
8.8 highCVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVE-2018-9846
High (8.8). EPSS 2.3% chance of exploitation in the next 30 days.
In Roundcube from versions 1.2.0 to 1.3.5, with the archive plugin enabled and configured, it's possible to exploit the unsanitized, user-controlled "_uid" parameter (in an archive.php _task=mail&_mbox=INBOX&_action=plugin.move2archive request) to perform an MX (IMAP) injection attack by placing an IMAP command after a %0d%0a sequence. NOTE: this is less easily exploitable in 1.3.4 and later because of a Same Origin Policy protection mechanism.
