Summary:

https://code4rena.com/reports/2022-08-olympus#h-01-in-governancesol-it-might-be-impossible-to-activate-a-new-proposal-forever-after-failed-to-execute-the-previous-active-proposal

Before any VOTES are minted anyone can activate and execute an arbitrary proposal even with 0 votes cast. So an attacker can pass any proposal (i.e. change the executor + admin of the Kernel, gaining access to all permissioned functions and to funds held).

Mitigation:

In Governance.sol check for a minimum VOTES totalSupply.
