Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-mx2j-7cmv-353c/ (Markdown: https://insights.sbomify.com/GHSA-mx2j-7cmv-353c/index.md)","id":"GHSA-mx2j-7cmv-353c","markdown":"https://insights.sbomify.com/GHSA-mx2j-7cmv-353c/index.md","name":"GHSA-mx2j-7cmv-353c","record":{"aliases":["GO-2025-3449"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CosmWasm VM library","requires_auth":"low_privilege","summary":"A malicious smart contract can slow down block production in CosmWasm chains, requiring library upgrades to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"# CWA-2025-002\n\n**Severity**\n\nMedium (Moderate + Likely)[^1]\n\n**Affected versions:**\n\n- wasmvm \u003e= 2.2.0, \u003c 2.2.2\n- wasmvm \u003e= 2.1.0, \u003c 2.1.5\n- wasmvm \u003e= 2.0.0, \u003c 2.0.6\n- wasmvm \u003c 1.5.8\n\n**Patched versions:**\n\n- wasmvm 1.5.8, 2.0.6, 2.1.5, 2.2.2\n\n## Description of the bug\n\nThe vulnerability can be used to slow down block production. The attack requires a malicious contract,\nso permissioned chains are unlikely to be affected.\n\n(We'll add more detail once chains had a chance to upgrade.)\n\n## Patch\n\n- 1.5: https://github.com/CosmWasm/cosmwasm/commit/2b7f2faa57a1efc8207455c37f87f1eee6035a27\n- 2.0: https://github.com/CosmWasm/cosmwasm/commit/d6143b0aff16a39bbea4be37597d8e9d9b213d3b\n- 2.1: https://github.com/CosmWasm/cosmwasm/commit/f0c04c03cbe2557634c1bbcdc2ce203fe7caca58\n- 2.2: https://github.com/CosmWasm/cosmwasm/commit/a5d62f65b5eb947ebe40e2085b1c48a9d0a244d0\n\n## Applying the patch\n\nThe patch will be shipped in releases of wasmvm. You can update more or less as follows:\n\n1. Check the current wasmvm version: `go list -m github.com/CosmWasm/wasmvm`\n2. Bump the `github.com/CosmWasm/wasmvm` dependency in your go.mod to one of the patched version\n   depending on which minor version you are on; `go mod tidy`; commit.\n3. If you use the static libraries `libwasmvm_muslc.aarch64.a`/`libwasmvm_muslc.x86_64.a`, update them accordingly.\n4. Check the updated wasmvm version: `go list -m github.com/CosmWasm/wasmvm` and ensure you see 1.5.8, 2.0.6, 2.1.5 or 2.2.2.\n5. Follow your regular practices to deploy chain upgrades.\n\nThe patch is consensus breaking and requires a coordinated upgrade.\n\n## Acknowledgement\n\nThis issue was found by meadow101 who reported
