CVE-2025-10761Network attack vector

Account compromise via unrestricted login attempts

Published Sep 21, 2025 · Updated Sep 22, 2025

Improper restriction of authentication attempts in Harness 3.3.0 allows remote attackers to guess credentials via /api/v1/login. The login endpoint accepts repeated authentication attempts without sufficient frequency controls, exposing a credential-guessing oracle. No authentication is required to send attempts, but exploitation has high complexity and disclosure requires successful credential guessing.
