An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-24044 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- hermes-engine (npm): affected all versions; fixed in 0.10.0\n- hermes-engine (npm): affected all versions; fixed in 0.10.0\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-2021-24044/ (Markdown: https://insights.sbomify.com/CVE-2021-24044/index.md)","id":"CVE-2021-24044","markdown":"https://insights.sbomify.com/CVE-2021-24044/index.md","name":"CVE-2021-24044","record":{"aliases":["GHSA-7mhc-prgv-r3q4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine","requires_auth":"none","summary":"A type confusion vulnerability in the Hermes JavaScript engine allows attackers to cause a segmentation fault and potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"hermes","vendor":"facebook"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"By passing invalid javascript code where await and yield were called upon non-async and non-generator getter/setter functions, Hermes would invoke generator functions and error out on invalid await/yield positions.
