Quick assessment

Affected
grokability snipe-it
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.

8.5.0 之前的 Snipe-IT 存在 SAML 断言重放漏洞，攻击者可利用 SAML ACS 处理器中非原子化的随机数（nonce）检查机制，复用已捕获的断言。攻击者可通过向 并发发送多个 POST 请求（携带同一已捕获断言），从而为受害者生成多个已认证的会话，并绕过由身份提供商（IdP）发起的会话撤销机制。

Vulnerability Description
Snipe-IT before 8.5.0 contains a SAML assertion replay vulnerability that allows attackers to reuse captured assertions by exploiting a non-atomic nonce check in the SAML acs handler. Attackers can send concurrent POST requests to /saml/acs with one captured assertion to obtain multiple authenticated victim sessions that evade IdP-driven revocation.
