Vulnerability Title
CVE-2026-9090
Source: NVD (National Vulnerability Database)
Vulnerability Description
Casdoor versions 2.362.0 and earlier contain a vulnerability that allows an attacker to bypass authentication by supplying an arbitrary signing certificate. The buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted pre-configured Identity Provider certificate, allowing an attacker to forge assertions signed with an attacker-controlled key.

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buildSpCertificateStore函数直接从传入的SAMLResponse中提取X.509证书，而非使用受信任的预配置身份提供商证书，允许攻击者提供任意签名证书绕过身份验证，从而伪造使用攻击者控制密钥签名的断言。
