It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-30266 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- wasmtime (PyPI): affected all versions up to 19.0.0; no fix listed\n- wasmtime (crates.io): affected from 19.0.0; fixed in 19.0.1\n- wasmtime (crates.io): affected from 19.0.0; fixed in 19.0.1\n- wasmtime (crates.io): affected from 19.0.0; fixed in 19.0.1\n\nTask:\n1. 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/CVE-2024-30266/ (Markdown: https://insights.sbomify.com/CVE-2024-30266/index.md)","id":"CVE-2024-30266","markdown":"https://insights.sbomify.com/CVE-2024-30266/index.md","name":"CVE-2024-30266","record":{"aliases":["DEBIAN-CVE-2024-30266","GHSA-75hq-h6g9-h4q5","PYSEC-2024-327","RUSTSEC-2024-0441","UBUNTU-CVE-2024-30266"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WebAssembly runtime","requires_auth":"low_privilege","summary":"A malicious WebAssembly module can cause the Wasmtime runtime to panic, leading to a denial of service for the host application.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"wasmtime","vendor":"bytecodealliance"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"wasmtime is a runtime for WebAssembly.
