Authentication Bypass in Cap-go OTP Verification
CVE-2026-56073 is an authentication bypass vulnerability affecting Cap-go versions prior to 12.128.2. The flaw exists in the OTP-based email verification workflow, where an attacker can intercept OTP verification requests and manipulate HTTP responses so that verification is incorrectly treated as successful. As described in the available content, this allows bypass of email verification controls and undermines the integrity of the OTP verification process. The issue appears to stem from improper trust in client-observable or modifiable response handling during verification rather than robust server-side validation.
