What is CVE-2026-114718?
CVE-2026-114718 is a medium-severity vulnerability in Roundcube Webmail, published on 22 Oct 2026.
Official description
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.
Weakness: CWE-79
