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/OSV-2021-875/ (Markdown: https://insights.sbomify.com/OSV-2021-875/index.md)","id":"OSV-2021-875","markdown":"https://insights.sbomify.com/OSV-2021-875/index.md","name":"OSV-2021-875","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"SerenityOS JS library","requires_auth":"none","summary":"A use-after-poison vulnerability in the SerenityOS JavaScript library allows attackers to cause memory corruption and potential code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35337\n\n```\nCrash type: Use-after-poison WRITE 8\nCrash state:\nAK::RefPtr\u003cAK::StringImpl, AK::RefPtrTraits\u003cAK::StringImpl\u003e \u003e::RefPtr\nAK::String::String\nJS::abstract_relation\n```","ecosystems":["OSS-Fuzz"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Use-after-poison in AK::RefPtr\u003cAK::StringImpl, AK::RefPtrTraits\u003cAK::StringImpl\u003e \u003e::RefPtr","id":"OSV-2021-875","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"serenity","purl":"pkg:generic/serenity","source":"OSV-2021-875"}],"products":null,"published":"2021-06-19","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"OSS-Fuzz","prefix":"OSV"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A use-after-poison vulnerability in the SerenityOS JavaScript library allows attackers to cause memory corruption and potential code execution.","url":"https://insights.sbomify.com/OSV-2021-875/"}
