AI Analysis
Technical Summary
The CosmWasm wasmd component had a vulnerability where multiple message types permitted the inclusion of a large number of addresses. This could lead to unexpected resource consumption during the ValidateBasic validation step, potentially impacting system performance or stability. The issue was fixed in wasmd version 0.52.0. The vulnerability is categorized under CWE-400 (Uncontrolled Resource Consumption) and has a CVSS 4.0 vector indicating network attack vector, high attack complexity, no privileges or user interaction required, and low impact on availability.
Potential Impact
The vulnerability may cause increased resource consumption during message validation, which could degrade performance or availability of the wasmd service. There are no known exploits in the wild. The impact is considered moderate due to the potential for resource exhaustion but no direct compromise or data loss.
Mitigation Recommendations
Upgrade to wasmd version 0.52.0 or later, where this vulnerability has been patched. No other mitigation steps are indicated.
