Name: ASA-2025-003: Groups module can halt chain when handling a malicious proposal Component: CosmosSDK Criticality: High (Considerable Impact; Likely Likelihood per ACMv1.2) Affected versions: <= v0.47.15, <= 0.50.11 Affected users: Validators, Full nodes, Users on chains that utilize the groups module
An issue was discovered in the groups module where a malicious proposal would result in a division by zero, and subsequently halt a chain due to the resulting error. Any user that can interact with the groups module can introduce this state.
The new Cosmos SDK release v0.50.12 and v0.47.16 fix this issue.
There are no known workarounds for this issue. It is advised that chains apply the update.
