Vulnerability description
DayBreach CVE AI Research
CVE-2026-96445 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
A flaw was found in the Conditional OTP authenticator of Keycloak, an identity and access management solution. The issue occurs when the system evaluates specific HTTP headers to determine if a one-time password (OTP) should be skipped, but fails to verify if those headers came from a trusted source. This could allow an attacker who already has a user's password to bypass the second-factor authentication by providing a specially crafted header in their request.
