Security hook should not be set in a NFT that is not Uniswap V3 Position NFT, otherwise the flash auction flow can be blocked.
If we look into the workflow of the flashAction, 
According to the documentation, the flashAction is implemented.
https://docs.astaria.xyz/docs/protocol-mechanics/flashactions
In the implementation above, if the security hook is set, the validation code runs:
and in the end of the flashAction:
If we look into the current implementation of the security hook:
The security hook should only applies to the Uniswap V3 Position NFT. However, in the current flashAction flow, if the security hook is set in a NFT that is not Uniswap V3 Position NFT, the security hook can revert the transaction and block the flashAction.
The security hook can be set via the file function in CollateralToken.sol
If we look into the source code of the Uniswap V3 Position Manager.sol
https://github.com/Uniswap/v3-periphery/blob/6cce88e63e176af1ddb6cc56e029110289622317/contracts/NonfungiblePositionManager.sol#L100
Note the line:
It is possible that if the security hook turns on for a NFT that is not for Uniswap V3 Position, the query of IV3PositionManager(positionManager).positions(tokenId) can revert the flashAction transaction.
We recommend the protocol validates the underlying NFT is a Uniswap V3 Position NFt if the security hook is set, otherwise, security hook should be disabled.
