Vulnerability Details

Currently, the protocol can use outdated price data for a period of three hours if the price goes stale before it halts the service. While the protocol is checking for stale data, is not providing a fallback or redundancy Oracle to keep providing a reliable service.

Recommendations

I recommend lowering PERIOD to a value closer to the actual heartbeats of the WETH/USD and WBTC/USD price feeds and integrate another oracles (e.g. Uniswap) to act as redundancy in the case of stale price data from Chainlink.
