# CVE-2026-116200: Snipe-IT before 8.6.3 LDAP StartTLS Downgrade via connectToLdap()

Status: published. Published: 2026-10-25. Updated: 2026-11-04.

Snipe-IT before 8.6.3 ignores the ldap_start_tls() return value in Ldap::connectToLdap(), allowing on-path attackers to force cleartext LDAP binds. Attackers can answer the StartTLS request with a protocol error to capture service-account credentials and end-user login passwords.
