  1. CVE-2026-114721

    Low · CVSS 3.1EPSS 0.3%Fix available

    CVE-2026-114721

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 allows the disabled_actions configuration setting to be bypassed. The check compared only the action name as requested, so a remote authenticated attacker could reach an action listed in disabled_actions by requesting it through its deprecated alias instead. Upstream fixed this in the commit “Fix bug where deprecated action aliases bypassed `disabled_actions` setting”, which moves the check into rcmail::action_handler() and resolves aliases before comparing.

    CVE-2026-114720

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an IMAP command injection vulnerability. A remote authenticated attacker can exploit this via CRLF sequences injected into the _flag parameter of the mail/mark action to execute arbitrary IMAP commands. Upstream fixed this in the commit “Fix IMAP command injection via CRLF in `_flag` parameter of mail/mark action”, which rejects flags containing control, whitespace and IMAP-special characters.

    CVE-2026-114719

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a CSRF validation bypass in the mark-as-junk action of the markasjunk plugin. The plugin read the _uid parameter from POST data but passed it to rcmail::get_uids() without constraining the input mode, so values re-read inside that helper could be taken from the query string and the action carried out without a valid CSRF token. Upstream fixed this in the commit “Fix CSRF validation bypass in the mark-as-junk action”, which passes rcube_utils::INPUT_POST explicitly.

  4. CVE-2026-114718

    CVE-2026-114718

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a cross-site scripting vulnerability in the password plugin. Error text returned by a password driver was concatenated into the message presented to the user without HTML escaping, so a backend able to influence that text, such as the DirectAdmin API, could inject script into the Roundcube interface. Upstream fixed this in the commit “Fix XSS issue in handling of password driver error responses”, which escapes the driver message before display.

    CVE-2026-114717

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability when a message is forwarded as an attachment. The subject of the forwarded message was used verbatim to generate the attachment name, so a received message whose subject contains CRLF sequences could inject arbitrary MIME part headers into the outgoing message. Upstream fixed this in the commit “Fix mail header injection via subject of a message forwarded as attachment”, which collapses whitespace in the generated name.

    CVE-2026-114716

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail::extract_inline_images() used the media type taken from an inline image data URI without validating it, so a remote authenticated attacker could inject arbitrary MIME part headers into the outgoing message by placing CRLF sequences in that media type. Upstream fixed this in the commit “Fix mail header injection via media type in an inline image data URI”, which validates the media type with rcube_mime::is_mimetype_valid().

    CVE-2026-114715

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an incorrect authorization vulnerability in the Modoboa driver of the password plugin. The driver took the first entry of the account search result returned by the Modoboa API instead of matching the authenticated user, so a password change could be applied to a different account. Upstream fixed this in the commit “Fix bug where Password Modoboa driver could change password for another account”, which selects the account whose username matches and fails if none does.

    CVE-2026-114714

    Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a path traversal vulnerability in the squirrelmail_usercopy plugin. With the file based backend, the source path was built from the login name without rejecting path separators, so a login name containing a slash could cause files outside the configured squirrelmail_data_dir to be read and imported. Upstream fixed this in the commit “Fix unsafe use of a login name in SquirrelMail import file path”, which rejects login names containing a slash.

    Important: php8.4 security update

    PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts.
