• Potential unauthorized password changes require verification and mitigation
• Defenders must verify and apply patches to prevent exploitation
• Affected systems require review and updates to ensure security

Technical summary

The Modoboa driver of the password plugin in Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an incorrect authorization vulnerability. The driver incorrectly takes the first entry of the account search result returned by the Modoboa API instead of matching the authenticated user, allowing a password change to be applied to a different account. This issue was fixed in Roundcube Webmail versions 1.6.20 and 1.7.5 by selecting the account whose username matches and failing if none does. Defenders should prioritize verifying and applying the patches to prevent potential unauthorized password changes.
