Juno Security Upgrade CWA-2021-003\n\nA critical security vulnerability has been found on wasmvm 0.13.x, 0.14.x, 0.15.x, 0.16.x and 1.x (link) user funds are not at risk but this could lead to a chain halt and consensus break.\n\nA patch for this security breach will be released with juno v2.2.x.\n\nThis signaling governance proposal is to amend the software version specified on proposal #9 from v2.1.x to v2.2.x. \n\nIn this way we can upgrade the chain in one time and have both moneta-patch and security patch live as quickly as possible.\n\n## Notes\n\n1. v2.2.0 is consensus breaking against v2.1.0, so it's very important that super-majority of validators runs correct version.\n2. Validators can follow the previousily shared instructions for the upgrade, but using the new version of the software.\n3. This proposal will still be in voting period during and after the upgrade. This doesn't really affect the upgrade process, but in case of rejection of this proposal validators should coordinate to cancel the upgrade or run the previous agreed version of the software.\n
