CVE-2026-93453 | BDVDB-2026-376555 Detail

Description#
SOGo before 5.12.11 constructs password-reset links using the client-supplied Origin header as the authority, allowing unauthenticated attackers to redirect recovery tokens to attacker-controlled domains. Attackers can submit password recovery requests with a malicious Origin header to have valid password-reset tokens mailed to victim recovery addresses within links pointing to attacker infrastructure, enabling account takeover.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact low. Attack vector: network.
Weaknesses#
- CWE-640 Weak Password Recovery Mechanism for Forgotten Password
