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.","vendor":"SimpleHelp","isMicrosoft":false,"products":[],"advisoryUrl":"https://simple-help.com/security/simplehelp-security-update-2026-05","publicExploit":null,"msrcUrl":"https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-48558","cisaUrl":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?search_api_fulltext=CVE-2026-48558"},"epss":null,"observedAt":"2026-10-23T16:01:26.7735792+00:00","kevRetained":false,"reviewIdentity":"837d6b2b71646a7a311248d2"}}
