Severity
8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Summary
e107 is a content management system (CMS). Prior to 2.3.4, a Host Header Injection vulnerability in the password reset page allows attackers to manipulate the Host header to generate password reset links pointing to attacker-controlled domains. This can lead to phishing attacks, account takeover, or other security risks. The severity is high, as the vulnerability affects a critical function related to user authentication. This vulnerability is fixed in 2.3.4.
