    CVE-2026-53660

    Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the default configuration initializes the iPlanetDirectoryPro SSO cookie with HttpOnly disabled and without a protective SameSite default, and OAuth and OpenID Connect consent flows reuse that cookie through CsrfProtection as a CSRF token. When combined with same-origin cross-site scripting and a user following an attacker-controlled link, the cookie can be read and reused to steal the SSO session and complete attacker-driven consent grants. This issue is fixed in version 16.1.1.
