Description
Netmaker through 1.7.0 contains an authorization bypass vulnerability in the updateExtClient handler that allows network-scoped users to modify external clients on other networks. Attackers with external client permissions on one network can send PUT requests to /api/extclients/{network}/{clientid} to replace public keys, disable clients, and obtain WireGuard private keys.
