Exposures › CVE-2026-48558
SimpleHelp's OIDC authentication flow accepts unsigned tokens, allowing remote attackers to forge credentials and bypass MFA.
This authentication bypass lets unauthenticated attackers inject forged identity tokens to gain full technician access, potentially bypassing MFA. For DIB orgs, this exposes sensitive systems to unauthorized access and violates FedRAMP requirements for identity verification. Immediate patching and OIDC configuration hardening are critical to prevent credential theft and session hijacking.
Shame score — A critical authentication bypass in a widely deployed vendor product that allows unauthenticated attackers to bypass MFA and gain full system access.
SimpleHelp contains 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.
