github.com/CosmWasm/wasmvm fixed: 1.5.4 
Upgrade github.com/CosmWasm/wasmvm to 1.5.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for cosmwasm-vm

How to Check if You Are Affected

To determine whether your application is affected by GHSA-rg2q-2jh9-447q, inspect your project dependencies for Cosmwasm vm:

inspect dependencies for cosmwasm-vm

Analyze the terminal output to locate any version of Cosmwasm vm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-920: Improper Restriction of Power Consumption, where the product operates in an environment in which power is a limited resource that cannot be automatically replenished, but the product does not properly restrict the amount of power that its operation consumes. In Cosmwasm vm, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

**Component:** wasmvm **Criticality:** Medium ([ACMv1](https://github.com/interchainio/security/blob/main/resources/CLASSIFICATION_MATRIX.md): I:Moderate; L:Likely) **Patched versions:** wasmvm 1.5.4, 2.0.3, 2.1.2 Some Wasm operations take significantly more gas than our benchmarks indicated. This can lead to missing the [gas target](https://github.com/CosmWasm/cosmwasm/blob/e50490c4199a234200a497219b27f071c3409f58/docs/GAS.md#cosmwasm-gas-pricing) we defined by a factor of ~10x. This means a malicious contract could take 10 times as much time to execute as expected, which can be used to temporarily DoS a chain. See [CWA-2024-004](https://github.com/CosmWasm/advisories/blob/main/CWAs/CWA-2024-004.md) for more details.
