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-2020-17534 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.netbeans.html:pom (Maven): affected all versions; fixed in 1.7.1\n- org.netbeans.html:pom (Maven): affected all versions; fixed in 1.7.1\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-2020-17534/ (Markdown: https://insights.sbomify.com/CVE-2020-17534/index.md)","id":"CVE-2020-17534","markdown":"https://insights.sbomify.com/CVE-2020-17534/index.md","name":"CVE-2020-17534","record":{"aliases":["GHSA-ppc3-fpvh-7396","UBUNTU-CVE-2020-17534"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Java HTML/Java API","requires_auth":"low_privilege","summary":"A race condition in the webkit subproject allows local attackers to escalate privileges by exploiting temporary file handling flaws.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"html\\/java_api","vendor":"apache"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"There exists a race condition between the deletion of the temporary file and the creation of the temporary directory in `webkit` subproject of HTML/Java API version 1.7.
