A critical authentication bypass vulnerability exists in Netmaker versions prior to 1.5.0. The VerifyHostToken function in logic/jwts.go fails to properly validate JWT signatures when verifying host tokens. This flaw allows attackers to forge JWT tokens signed with arbitrary keys to impersonate any host in the network. Successful exploitation grants unauthorized access to sensitive information within the Netmaker network infrastructure. The vulnerability affects the core authentication mechanism of the Netmaker network management platform.
