Vulnerability details

Proof of Concept

Using StateTransitionManager.freezeChain function admin can freeze specific chain. This means that all non freezable facets will not be callable anymore.

StateTransitionManager.unfreezeChain function should do the opposite action, however it by mistake calls freeze as well, which means that it will be not possible to unfreeze proxy.

Impact

Not possible to unfreeze proxy. Need to do upgrade.

Tools Used

VsCode

Recommended Mitigation Steps

Use correct function to unfreeze.
