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-2021-24045 in the wild and no public exploit code.\n\nAffected product: Facebook Hermes. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-24045/ (Markdown: https://insights.sbomify.com/CVE-2021-24045/index.md)","id":"CVE-2021-24045","markdown":"https://insights.sbomify.com/CVE-2021-24045/index.md","name":"CVE-2021-24045","record":{"aliases":["GHSA-7493-f24p-jv53"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"JavaScript engine","requires_auth":"none","summary":"Type confusion in Hermes allows code execution if untrusted JavaScript is evaluated, affecting React Native apps with this configuration.","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":"A type confusion vulnerability could be triggered when resolving the \"typeof\" unary operator in Facebook Hermes prior to v0.10.0.
