CVE-2025-1397— Improper IDP Status Validation via JWT Bearer or SAML2 Bearer Grants in Multiple WSO2 Products Allows Access Token Issuance for Disabled Identity Providers

Quick assessment

Affected
WSO2 WSO2 Universal Gateway
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

当使用 JWT Bearer 或 SAML2 Bearer 授权类型时，系统在颁发访问令牌前未能验证身份提供商（IDP）的状态。这一疏忽导致即使相关 IDP 已被禁用，系统仍会生成访问令牌。 攻击者可利用此漏洞，针对已禁用的 IDP 获取访问令牌，从而绕过预设的安全控制措施，并可能访问本应因 IDP 被禁用而无法访问的受保护资源。

Vulnerability Title
Improper IDP Status Validation via JWT Bearer or SAML2 Bearer Grants in Multiple WSO2 Products Allows Access Token Issuance for Disabled Identity Providers
Source: CVE Program / CVE List V5
Vulnerability Description
When utilizing JWT Bearer or SAML2 Bearer grant types, the system fails to validate the status of the Identity Provider (IDP) before issuing access tokens. This oversight permits tokens to be generated even when the associated IDP has been disabled. A malicious actor could leverage this vulnerability to obtain access tokens by targeting a disabled IDP. This could enable them to bypass intended security controls and potentially access protected resources that should be inaccessible due to the IDP's disabled state.
