rcubeimage.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell metacharacters in a configuration setting for imconvertpath or imidentifypath.

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.

rcubeutils.php in Roundcube before 1.1.8 and 1.2.x before 1.2.4 is susceptible to a cross-site scripting vulnerability via a crafted Cascading Style Sheets (CSS) token sequence within an SVG element.

Roundcube Webmail allows arbitrary password resets by authenticated users. This affects versions before 1.0.11, 1.1.x before 1.1.9, and 1.2.x before 1.2.5. The problem is caused by an improperly restricted exec call in the virtualmin and sasl drivers of the password plugin.
