Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
Missing Auth describes the vulnerability class recorded for this advisory. NVD marks CVE-2026-48558 as known exploited, so exposure review should be prioritized. This is a product-level record in the current feed, not a package-level dependency mapping.
Affected software not mapped. Review the upstream record for vendor-specific product and version guidance.
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.
Reported by NVD (nvd).
