CVE-2020-5268 is a high-severity vulnerability affecting Sustainsys.Saml2 Authentication Services versions before 1.0.2 and between 2.0.0 and 2.6.0. The flaw stems from the library incorrectly treating all incoming SAML2 tokens as bearer tokens, even when other subject confirmation methods are specified. This could allow an attacker to bypass authentication by using a specially crafted SAML2 token to establish a login session. The vulnerability has a CVSS score of 7.3 (High), indicating a network-based attack with low attack complexity, requiring low privileges and user interaction, and leading to high confidentiality and integrity impacts. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
