An issue was discovered in Roundcube Webmail before 1.4.4. A CSRF attack can cause an authenticated user to be logged out because POST was not considered.
CVE-2020-12625 3 Debian, Opensuse, Roundcube 4 Debian Linux, Backports Sle, Leap and 1 more 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in Roundcube Webmail before 1.4.4. There is a cross-site scripting (XSS) vulnerability in rcube_washtml.php because JavaScript code can occur in the CDATA of an HTML message.
CVE-2019-15237 2 Fedoraproject, Roundcube 2 Fedora, Webmail 2026-06-17 4.3 MEDIUM 7.4 HIGH
Roundcube Webmail through 1.3.9 mishandles Punycode xn-- domain names, leading to homograph attacks.
CVE-2019-10740 3 Fedoraproject, Opensuse, Roundcube 4 Fedora, Backports Sle, Leap and 1 more 2026-06-17 4.3 MEDIUM 4.3 MEDIUM
In Roundcube Webmail before 1.3.10, an attacker in possession of S/MIME or PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, they unknowingly leak the plaintext of the encrypted message part(s) back to the attacker.
CVE-2018-9846 2 Debian, Roundcube 2 Debian Linux, Webmail 2026-06-17 6.8 MEDIUM 8.8 HIGH
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.
CVE-2018-19206 2 Debian, Roundcube 2 Debian Linux, Webmail 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
steps/mail/func.inc in Roundcube before 1.3.8 has XSS via crafted use of <svg><style>, as demonstrated by an onload attribute in a BODY element, within an HTML attachment.
CVE-2018-19205 1 Roundcube 1 Webmail 2026-06-17 5.0 MEDIUM 7.5 HIGH
Roundcube before 1.3.7 mishandles GnuPG MDC integrity-protection warnings, which makes it easier for attackers to obtain sensitive information, a related issue to CVE-2017-17688. This is associated with plugins/enigma/lib/enigma_driver_gnupg.php.
CVE-2018-1000071 1 Roundcube 1 Webmail 2026-06-17 5.0 MEDIUM 7.5 HIGH
roundcube version 1.3.4 and earlier contains an Insecure Permissions vulnerability in enigma plugin that can result in exfiltration of gpg private key. This attack appear to be exploitable via network connectivity.
CVE-2017-8114 1 Roundcube 1 Webmail 2026-06-17 6.5 MEDIUM 8.8 HIGH
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.
CVE-2017-6820 1 Roundcube 1 Webmail 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
rcube_utils.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.
CVE-2017-17688 11 Apple, Bloop, Emclient and 8 more 11 Mail, Airmail, Emclient and 8 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
The OpenPGP specification allows a Cipher Feedback Mode (CFB) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL. NOTE: third parties report that this is a problem in applications that mishandle the Modification Detection Code (MDC) feature or accept an obsolete packet type, not a problem in the OpenPGP specification
CVE-2017-16651 2 Debian, Roundcube 2 Debian Linux, Webmail 2026-06-17 4.6 MEDIUM 7.8 HIGH
Roundcube Webmail before 1.1.10, 1.2.x before 1.2.7, and 1.3.x before 1.3.3 allows unauthorized access to arbitrary files on the host's filesystem, including configuration files, as exploited in the wild in November 2017. The attacker must be able to authenticate at the target system with a valid username/password as the attack requires an active session. The issue is related to file-based attachment plugins and _task=settings&_action=upload-display&_from=timezone requests.
CVE-2016-9920 1 Roundcube 1 Webmail 2026-06-17 6.0 MEDIUM 7.5 HIGH
steps/mail/sendmail.inc in Roundcube before 1.1.7 and 1.2.x before 1.2.3, when no SMTP server is configured and the sendmail program is enabled, does not properly restrict the use of custom envelope-from addresses on the sendmail command line, which allows remote authenticated users to execute arbitrary code via a modified HTTP request that sends a crafted e-mail message.
CVE-2016-4552 1 Roundcube 1 Webmail 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
Cross-site scripting (XSS) vulnerability in Roundcube Webmail before 1.2.0 allows remote attackers to inject arbitrary web script or HTML via the href attribute in an area tag in an e-mail message.
CVE-2016-4069 2 Opensuse, Roundcube 2 Leap, Webmail 2026-06-17 6.8 MEDIUM 8.8 HIGH
Cross-site request forgery (CSRF) vulnerability in Roundcube Webmail before 1.1.5 allows remote attackers to hijack the authentication of users for requests that download attachments and cause a denial of service (disk consumption) via unspecified vectors.
