AI-suggested
A fix is available in Alinto SOGo version 5.12.11 and later. Users should upgrade to version 5.12.11 or newer to remediate this vulnerability. Until upgrading, avoid relying on the Origin header for constructing password reset links or implement server-side validation to ensure links are not redirected to untrusted domains.
Description
CVE-2026-93453 is a high-severity vulnerability in Alinto SOGo versions prior to 5.12.11. The issue arises from the password recovery mechanism using the client-supplied Origin header to build password reset links. This flaw allows unauthenticated attackers to craft malicious Origin headers, causing password reset emails to contain links pointing to attacker-controlled domains. This can potentially enable account takeover by redirecting users to malicious sites during password recovery.
