CVE-2025-46739Network attack vector

Credential discovery via unrestricted authentication attempts

Published May 12, 2025 · Updated May 12, 2025

Authentication throttling failure in SEL Blueframe OS before 1.12.0 allows remote attackers to discover account credentials by brute force. SEL has not disclosed the affected authentication endpoint or implementation details beyond the absence of rate limiting on repeated guesses. No authentication or user interaction is required; successful guessing exposes a valid account and the access granted to it.
