CVE-2026-86770 PUBLISHED

Snipe-IT before 8.7.0 Authentication Bypass via SAML Username Collation

Assigner: VulnCheck
Reserved: 08.09.2026 Published: 09.09.2026 Updated: 09.09.2026

Snipe-IT before 8.7.0 fails to validate username case sensitivity during SAML authentication, allowing attackers to authenticate as different users by registering IdP accounts with accent or case variants of victim usernames. Attackers can exploit the default utf8mb4_unicode_ci database collation to bypass username matching and achieve account takeover through federated login paths including SAML, LDAP, and OAuth.
