Reentrancy in ERC1967Upgrade._upgradeToAndCallSecure(address,bytes,bool) (#496-524):
External calls:
- Address.functionDelegateCall(newImplementation,data) (#506)
- Address.functionDelegateCall(newImplementation,abi.encodeWithSignature(upgradeTo(address),oldImplementation)) (#514-517)
Event emitted after the call(s):
- Upgraded(newImplementation) (#472)
- _upgradeTo(newImplementation) (#522)
Apply the check-effects-interactions pattern.

Contract name (UST (Wormhole)) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Contract ownership is semi-renounced (passed to a contract)

Low level call in Address.functionStaticCall(address,bytes,string) (#241-250):
- (success,returndata) = target.staticcall(data) (#248)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
