CVE-2026-68745— Apache CloudStack: SAML2 Signature Validation Silently Skipped for Cert-less IdP
Quick assessment
Affected
Apache Software Foundation Apache CloudStack
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.
在 Apache CloudStack 4.20.3.0 和 4.22.1.0 版本中，所有平台上的 SAML 认证存在证书验证失败的问题。该漏洞允许恶意代理伪造发送至管理服务器的 SAML 响应。攻击者需要先伪装身份提供商（IdP）的 IP 地址，或将自行选择的 URL 注册到管理服务器中，随后便可使用伪造的数字签名进行登录。 建议用户升级到 4.20.3.1 或 4.22.1.1 及更高版本，这些版本已修复该安全问题。

Vulnerability Title
Apache CloudStack: SAML2 Signature Validation Silently Skipped for Cert-less IdP
Source: CVE Program / CVE List V5
Vulnerability Description
Certificate validation failures in SAML authentication in Apache CloudStack 4.20.3.0 and 4.22.1.0 on all platforms allow a malicious agent to forge a SAML response to the management server. The agent will have to spoof the ip address of the IdP or get an url of its own choosing registered in the management server, after which it can allow logging on with forged signatures.
Users are recommended to upgrade to versions 4.20.3.1 or 4.22.1.1 and above, which fix this issue.
