CVE-2026-56081
Cap-go Authentication Logic Flaw Allows Account Takeover
Halo Surface Signal: 4 out of 5 — likely to be public-facing.
A flaw in Cap-go's authentication logic allows an attacker to register and control an account using a victim's email address before it's verified. This enables an attacker to gain full account control, including policy enforcement, while denying access to the legitimate user.
