CVE-2026-116200 · Severity: medium · CVSS 5.9 · Published 2026-10-25

Snipe-IT is an asset management system that uses LDAP for user authentication. A flaw in its LDAP connection code allows attackers positioned on the network path between Snipe-IT and the LDAP server to silently downgrade the connection to cleartext, capturing both LDAP service-account credentials and user passwords without triggering any errors or alerts.

## How to fix

- Fixed in 8.6.3

## Technical details

Snipe-IT's Ldap::connectToLdap() method calls PHP's ldap_start_tls() but ignores the return value, failing to detect when StartTLS negotiation fails (CWE-757, CWE-319). An on-path attacker can respond to the StartTLS request with a protocol error, causing ldap_start_tls() to return false, yet the code proceeds to ldap_bind() over the now-cleartext connection. This exposes both service-account credentials and end-user passwords on every LDAP operation.
