Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-287.

Summary

EspoCRM before 10.0.6 has an authentication bypass in which a login stopped at the second factor is accepted on routes that do not require authentication. An attacker who knows a 2FA-enabled user's username and password can skip the second factor and read configuration parameters that are not exposed publicly, as described in CWE-287. The CVSS 4.0 vector requires low privileges and no user interaction over the network.
