CVE-2026-2676Public exploitNetwork attack vector

Authenticated privilege escalation via session-only authorization

Published Feb 18, 2026 · Updated Feb 18, 2026

Authorization bypass in GoogTech sms-ssm at e8534c766fd13f5f94c01dab475d75f286918a8d allows remote authenticated users to access administrator APIs. LoginInterceptor.preHandle checks only whether the HTTP session contains a user and never verifies that the stored user type is authorized, while AdminController endpoints add no separate role check. Any student account and its session cookie therefore reach administrator operations outside the student's intended permissions.
