  - 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-2020-12625)

  - 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-2020-12626)

  - Roundcube Webmail before 1.4.4 allows attackers to include local files and execute code via directory
    traversal in a plugin name to rcube_plugin_api.php. (CVE-2020-12640)

  - rcube_image.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell
    metacharacters in a configuration setting for im_convert_path or im_identify_path. (CVE-2020-12641)

  - An issue was discovered in Roundcube Webmail before 1.3.12 and 1.4.x before 1.4.5.
    include/rcmail_output_html.php allows XSS via the username template object. (CVE-2020-13964)

  - An issue was discovered in Roundcube Webmail before 1.3.12 and 1.4.x before 1.4.5. There is XSS via a
    malicious XML attachment because text/xml is among the allowed types for a preview. (CVE-2020-13965)

  - An issue was discovered in Roundcube Webmail before 1.2.11, 1.3.x before 1.3.14, and 1.4.x before 1.4.7.
    It allows XSS via a crafted HTML e-mail message, as demonstrated by a JavaScript payload in the xmlns (aka
    XML namespace) attribute of a HEAD element when an SVG element exists. (CVE-2020-15562)

  - Roundcube Webmail before 1.3.15 and 1.4.8 allows stored XSS in HTML messages during message display via a
    crafted SVG document. This issue has been fixed in 1.4.8 and 1.3.15. (CVE-2020-16145)

  - An XSS issue was discovered in Roundcube Webmail before 1.2.13, 1.3.x before 1.3.16, and 1.4.x before
    1.4.10. The attacker can send a plain text e-mail message, with JavaScript in a link reference element
    that is mishandled by linkref_addindex in rcube_string_replacer.php. (CVE-2020-35730)

  - Roundcube before 1.3.17 and 1.4.x before 1.4.12 is prone to XSS in handling an attachment's filename
    extension when displaying a MIME type warning message. (CVE-2021-44025)

  - Roundcube before 1.3.17 and 1.4.x before 1.4.12 is prone to a potential SQL injection via search or
    search_params. (CVE-2021-44026)

  - Roundcube before 1.4.13 and 1.5.x before 1.5.2 allows XSS via an HTML e-mail message with crafted
    Cascading Style Sheets (CSS) token sequences. (CVE-2021-46144)
