CVE-2026-48558 (GCVE-0-2026-48558)

Vulnerability from cvelistv5 – Published: 2026-06-12 17:07 – Updated: 2026-06-13 03:56

Title
SimpleHelp Authentication Bypass via Missing OIDC JWT Signature Verification
Summary
SimpleHelp versions 5.5.15 and prior and 6.0 pre-release versions contain an authentication bypass vulnerability in the OIDC authentication flow. When OIDC authentication is configured, identity tokens submitted during login are accepted without verifying their cryptographic signature. In a vulnerable configuration, a remote, unauthenticated attacker can submit a forged token containing arbitrary identity claims to obtain a fully authenticated technician session. In some configurations, this may also allow bypass of multi-factor authentication. No user interaction is required.
