Improper authentication on SAML SSO process allows user impersonation in sentry

Sentry is a developer-first error tracking and performance monitoring tool. A critical vulnerability was discovered in the SAML SSO implementation of Sentry. It was reported to us via our private bug bounty program. The vulnerability allows an attacker to take over any user account by using a malicious SAML Identity Provider and another organization on the same Sentry instance. The victim email address must be known in order to exploit this vulnerability. The Sentry SaaS fix was deployed on Jan 14, 2025. For self hosted users; if only a single organization is allowed `(SENTRY_SINGLE_ORGANIZATION = True)`, then no action is needed. Otherwise, users should upgrade to version 25.1.0 or higher. There are no known workarounds for this vulnerability.

认证机制不恰当

Sentry 授权问题漏洞

Sentry是Sentry开源的一个面向开发人员的错误跟踪和性能监控平台。 Sentry 25.1.0之前版本存在授权问题漏洞，该漏洞源于允许攻击者通过使用恶意SAML身份提供者和同一Sentry实例上的另一个组织来接管任何用户帐户。
