CVE-2025-62604Network attack vector

Unauthenticated account takeover via authentication-mode selection

Published Oct 22, 2025 · Updated Oct 22, 2025

Authentication bypass in FIT2CLOUD MeterSphere before 2.10.25-lts allows remote attackers to sign in as any user without a password. The /signin controller passed the request's attacker-selected authenticate value to UserLoginService, which treated OIDC, CAS, OAuth2, or LDAP as third-party login and created a session from the supplied username without local password verification. Exploitation requires network access to the sign-in route and a valid target username, granting that user's application access.
