Doc Text:	A flaw was found in roundcubemail. The password plugin does not properly sanitize error messages returned by password drivers before displaying them in the web interface. A remote attacker or backend service capable of controlling these error responses can execute arbitrary script code in the context of the user's browser session through Cross-Site Scripting (XSS).

Description OSIDB Bzimport 2026-10-22 01:47:05 UTC

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.
