Vulnerability Title
CVE-2026-9093
Source: NVD (National Vulnerability Database)
Vulnerability Description
In Casdoor versions 2.362.0 and earlier, the SAML service provider implementation does not validate the AudienceRestriction element in SAML assertions. The buildSp function in object/saml_sp.go never sets AudienceURI on the gosaml2 SAMLServiceProvider struct and never inspects WarningInfo.NotInAudience. This allows assertions issued for other service providers to be accepted by Casdoor.

Casdoor 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Casdoor是Casdoor开源的一个支持多种身份验证和授权协议的开源平台。 Casdoor 2.362.0及之前版本存在安全漏洞，该漏洞源于SAML服务提供商实现未验证SAML断言中的AudienceRestriction元素，因为object/saml_sp.go中的buildSp函数从未在gosaml2 SAMLServiceProvider结构上设置AudienceURI，也从未检查WarningInfo.NotInAudience，这允许为其他服务提供商发布的断言被Casdoor接受。
