Can a Malicious Actor Exploit the Proxy’s Upgrade Mechanism?

Yes, if the upgrade mechanism is not properly secured, a malicious actor who gains control of the admin key can point the proxy to a new, malicious logic contract. This new contract could contain code to drain funds, halt operations, or steal user data.

This is a primary security concern and necessitates robust security measures like multi-signature wallets and time-locks.
