An attacker in possession of the signing key can craft valid JWT tokens impersonating arbitrary users within a OneLogin tenant. The tokens allow authentication to the OneLogin SSO portal and all downstream applications federated via SAML or OIDC. This allows full unauthorized access across the victim\u2019s SaaS environment.\n\ud83d\udccf Published: 2025-07-01T14:49:25.544Z\n\ud83d\udccf Modified: 2025-07-01T14:49:25.544Z\n\ud83d\udd17 References:\n1. https://support.onelogin.com/product-notification/noti-00001768\n2. https://specterops.io/blog/2025/06/10/onelogin-many-issues-how-i-pivoted-from-a-trial-tenant-to-compromising-customer-signing-keys/\n3. https://vulncheck.com/advisories/onelogin-ad-connector-account-compromise", "creation_timestamp": "2025-07-01T15:07:59.000000Z"}]}
