Teams running Kong Gateway Enterprise with the SAML plugin enabled for single sign-on are exposed: the plugin does not check that a SAML assertion was issued for this Kong, so a valid assertion issued for another service provider can be replayed to log in. Deployments without the SAML plugin, and open-source Kong, are not affected. Affected ranges per the CVE record (via OffSeq): >=3.10.0.0 <3.10.0.20, >=3.13.0.0 <3.13.0.12, >=3.14.0.0 <3.14.0.17, >=3.15.0.0 <3.15.0.7, >=3.16.0.0 <3.16.0.2.
