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，该漏洞源于未强制执行SAML断言时间范围，因为gosaml2库在assertionInfo.WarningInfo字段中报告所有时间验证结果，包括NotOnOrAfter和NotBefore，但ParseSamlResponse从未读取此字段，时间范围由库计算但在用户会话发出前被静默丢弃。

Vulnerability Title
CVE-2026-9096
Source: CVE Program / CVE List V5
Vulnerability Description
Casdoor versions 2.362.0 and earlier do not enforce SAML assertion time bounds. The gosaml2 library reports all time-validation results, including NotOnOrAfter and NotBefore, in the assertionInfo.WarningInfo field. However, ParseSamlResponse() never reads this field, meaning that time bounds are computed by the library but silently discarded before the user session is issued.
