Doc Text:
A flaw was found in Roundcube Webmail. This vulnerability allows an authenticated remote user to take over another account through unauthorized password modification. When a password change is requested, the Modoboa driver in the password plugin selects the first account returned by the API search rather than verifying it matches the authenticated user. Consequently, an attacker can overwrite the credentials of a different user account.

Description OSIDB Bzimport 2026-10-22 01:45:08 UTC 
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.
