Impact
In PeriodicVestingAccount, defined in x/auth, an attacker can initialize a victim's account as a malicious vesting account, which allows deposits but does not allow withdrawals. When the user then deposits funds into their account, those funds are locked forever, and the user is not able to withdraw them.
Patches
>= v0.46.13 for Cosmos SDK v0.46.x
>= v0.47.3 for Cosmos SDK v0.47.x
If a network backported periodic vesting accounts to earlier versions of the SDK, those networks are affected too.
Workarounds
There is no workaround for this issue. Upgrade immediately.
