## Overview

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.

## Affected

- `snipe-it < 8.5.0`

## Remediation
