CVE-2026-116201 Oct 25, 2026 Source: Vendor
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.
