Missing implementation of ClonedCoolDownHolder:rescueTokens inside the PendlePTKelpVault and PendlePTStakedUSDeVault vaults

Summary

The function ClonedCoolDownHolder:rescueTokens is not implemented and can't be called by the vaults PendlePTKelpVault and PendlePTStakedUSDeVault.

Vulnerability Detail

The function ClonedCoolDownHolder:rescueTokens has the onlyVault modifier, so it can only be called by the vault. However the PendlePTKelpVault and PendlePTStakedUSDeVault have no implementation and no way to call the ClonedCoolDownHolder:rescueTokens functions.

Impact

The recovery of lost tokens in the vaults PendlePTKelpVault and PendlePTStakedUSDeVault can't be done, since the vaults have no way to call the function ClonedCoolDownHolder:rescueTokens, which can only be called by the vault. Thus, lost tokens may be stuck in the vault forever.

Tool used

Manual Review

Recommendation

Consider implementing some functionality into the vaults PendlePTKelpVault and PendlePTStakedUSDeVault to call ClonedCoolDownHolder:rescueTokens, so that lost tokens can be recovered by these vaults.
