CVE-2026-116201 · Severity: high · CVSS 8.8 · Published 2026-10-25

Snipe-IT is an asset management platform that uses SAML authentication to verify user identity through an identity provider. An attacker who intercepts a single valid login assertion can replay it multiple times in quick succession to create multiple authenticated sessions for the same user, bypassing the identity provider's ability to revoke access through normal channels.

## How to fix

- Fixed in 8.5.0

## Technical details

The vulnerability is a capture-replay flaw combined with a time-of-check time-of-use (TOCTOU) race condition in the SAML assertion handler (/saml/acs). The saml_nonces table uses a non-unique index on the nonce column and lacks transaction-level protection, allowing concurrent POST requests with the same captured assertion to both pass the nonce existence check and both execute Auth::login(), creating two parallel sessions from one assertion. An attacker needs network access to capture a valid SAML assertion (via MITM, malicious browser extension, or log leakage) and the ability to submit the assertion twice within a sub-second race window.
