Overview<\/strong><\/p>\n

In the constantly evolving landscape of cybersecurity, a new vulnerability has been discovered that affects Zitadel, an open-source identity infrastructure software. Identified as CVE-2025-48936, this vulnerability presents certain risks to users and poses a significant threat to the security of their accounts. The vulnerability exists in the password<\/a> reset mechanism of Zitadel versions prior to 2.70.12, 2.71.10, and 3.2.2. The implications of this flaw are substantial, potentially leading to system compromise or data leakage<\/a>, making it a critical issue to be addressed promptly.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-48936
\nSeverity: High – CVSS Score 8.1
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Potential system compromise or data<\/a> leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Zitadel | Prior to 2.70.12
\nZitadel | Prior to 2.71.10
\nZitadel | Prior to 3.2.2<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a flaw in the password reset<\/a> mechanism of Zitadel. The software uses the Forwarded or X-Forwarded-Host header<\/a> from incoming requests to construct the URL for the password reset confirmation link that is emailed to the user. If an attacker can manipulate these headers<\/a>, for instance, via host header injection, they could cause Zitadel to generate a password reset link pointing to a malicious domain under their control. If the unsuspecting user clicks this manipulated link, the secret reset code embedded in the URL<\/a> can be captured by the attacker. This code can then be used to reset the user’s password and gain unauthorized access<\/a> to their account.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited. The attacker sends a malicious HTTP request<\/a> manipulating the “X-Forwarded-Host” header:<\/p>\n

POST \/password\/reset HTTP\/1.1\nHost: victim.example.com\nX-Forwarded-Host: attacker.com\nContent-Type: application\/json\n{ \"email\": \"victim@example.com\" }<\/code><\/pre>\n
This causes the password reset email to include a link pointing to the attacker’s domain, which enables them to capture the user’s reset code<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
