AI Analysis
Technical Summary
In Roundcube Webmail versions prior to 1.6.18 and 1.7.x prior to 1.7.3, the modoboa driver of the password plugin can leak a Modoboa API authentication token to a user-controlled host through crafted session data. This issue specifically affects Roundcube instances that use the password plugin configured with the modoboa driver. The vulnerability is tracked as CVE-2026-75010 and is associated with CWE-669 (Improper Control of a Resource Through its Lifetime).
Potential Impact
An attacker with low privileges (local user) can cause the leakage of a Modoboa API authentication token, potentially compromising confidentiality and integrity of the affected system's API interactions. There is no indication of availability impact. The vulnerability requires no user interaction and has network attack vector, making it moderately impactful.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using the password plugin with the modoboa driver or restrict access to trusted users only. Monitor vendor channels for updates and apply patches once released.
