LinkAce: Password Reset Poisoning via X-Forwarded-Host Header Injection Leading to Account Takeover_CVE-2026-40905

{
    "lastseen": "",
    "description": "LinkAce is a self-hosted archive to collect website links. Prior to 2.5.4, a password reset poisoning vulnerability was identified in the application due to improper trust of user-controlled HTTP headers. The application uses the X-Forwarded-Host header when generating password reset URLs. By manipulating this header during a password reset request, an attacker can inject an attacker-controlled domain into the reset link sent via email. As a result, the victim receives a password reset email containing a malicious link pointing to an attacker-controlled domain. When the victim clicks the link, the password reset token is transmitted to the attacker-controlled server. An attacker can capture this token and use it to reset the victim\u2019s password, leading to full account takeover. This vulnerability is fixed in 2.5.4.",
