CVE-2026-67595

VaahCMS versions 2.0.0 through 2.3.4 contain a hidden JavaScript payload in the OTP email template that can run code in browsers that open the email. The script connects to a command‑and‑control server, logs passwords, scrapes WhatsApp Web, and can redirect or overwrite the page.

01

Who is affected

VaahCMS 2.0.0–2.3.4, used by sites that send OTP emails.

02

Real-world impact

An attacker can run arbitrary code in a victim’s browser when they open the OTP email, allowing password logging, data theft from WhatsApp Web, and page manipulation.

03

Why this severity

The CVSS score of 9.2 reflects that the flaw allows remote code execution without authentication, with high impact on confidentiality, integrity, and availability, and is easily exploitable over the network.

04

What to do about it

no official fix yet
interim mitigations
  • Avoid opening OTP emails from VaahCMS until a patch is released.
