Name: ISA-2025-002: x/group can halt when erroring in EndBlocker
Component: CosmosSDK

Affected versions: <= v0.47.16, <= 0.50.12
Affected users: Validators, Full nodes, Users on chains that utilize the groups module
Cosmos SDK chains in unpatched releases that use the
x/group module are affected.Description
An issue was discovered in the groups module where malicious proposals would result in an errors triggered in the module's end blocker that could result in a chain halt. Any set of users that can interact with the groups module could introduce this state.
Patches
Has the problem been patched? What versions should users upgrade to?
Testing
Testing we have done to gain more confidence in this release:
In addition to testing Cosmos SDK we also did the following:
- Ran a patched node in a local
v0.50testnet with the failing state and did not halt (an unpatched network confirmed to halt) - Ran a patched node on Xion Mainnet (uses
x/group) - Ran a patched node on Zetachain Mainnet (uses
x/xgroup)
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
There are no known workarounds for this issue. It is advised that chains apply the update.
