CVE-2022-31164Network attack vector

Unauthenticated privileged-account impersonation

Published Jul 21, 2022 · Updated Apr 23, 2025

Improper authentication in Tovyblox Tovy before 0.7.51 allows remote attackers to impersonate any user, including privileged users. The public advisory identifies the login flow but does not disclose the request field, function, or validation error that accepts another user's identity. No credentials or user interaction are required, and successful exploitation grants the impersonated account's permissions.
