{"id":"CVE-2026-114718","kind":"vulnerability","aliases":["CVE-2026-114718"],"related":[],"title":"Roundcube Webmail: password plugin error text lets script run in webmail","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.","summary":"Roundcube's password plugin inserts error text from a password backend into the page without HTML escaping.
