CVE-2025-46742Network attack vector

Authenticated system access before mandatory password change

Published May 12, 2025 · Updated Oct 1, 2025

Improper authentication in SEL Blueframe OS before 1.12.0 allows remote authenticated users to access system information. SEL has not published the endpoint or authorization logic that fails to enforce the mandatory-password-change gate. A valid account flagged for password replacement is required, and the resulting access is limited to system information before that replacement.
