Name of the Vulnerable Software and Affected Versions Invoice Ninja versions prior to 5.13.27

Description An open redirect exists in the client portal login. Unauthenticated attackers can redirect authenticated users to external URLs by injecting a malicious value into the intended query parameter. This value is stored in the session without host validation and is processed by the ContactLoginController authenticated() handler, which performs a bare redirect after a legitimate login, facilitating phishing attacks.
