This test is designed to reproduce an infinite Feegrant bug that occurs when using AllowedMsgAllowance with an internal BasicAllowance. I suspect that this line (https://github.com/scrtlabs/cosmos-sdk/blob/61091b357e/x/feegrant/basic_fee.go#L31) does not update the internal BasicAllowance after using part of the grant. This may be related to this line (https://github.com/scrtlabs/cosmos-sdk/blob/61091b357e/x/feegrant/filtered_fee.go#L47) as well.
The internal allowance update in AllowedMsgAllowance was never propagated to the parent AllowedMsgAllowance.

What is the impact of such bug? Given that v0.45.x is EOL, only security fixes are included in this branch. |
