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-2026-82430 in the wild and no public exploit code.\n\nAffected product: Apache Storm Worker Launcher. 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-2026-82430/ (Markdown: https://insights.sbomify.com/CVE-2026-82430/index.md)","id":"CVE-2026-82430","markdown":"https://insights.sbomify.com/CVE-2026-82430/index.md","name":"CVE-2026-82430","record":{"aliases":["GHSA-pjcp-2m43-fmv9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Apache Storm worker launcher","requires_auth":"low_privilege","summary":"A race condition in Apache Storm's worker launcher allows local attackers to escalate privileges to root by modifying command files during container startup.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Description\n\nWhen launching a Docker or OCI worker, the setuid-root `worker-launcher` first changes ownership of the\nentire worker directory to the untrusted topology user, and only afterwards reads and acts on the command\nfile that the supervisor wrote into that same directory. The file is opened without `O_NOFOLLOW` and without\nre-verifying its owner, so between the ownership change and the read the tenant can replace its contents.\n\nFor the Docker path the parsed command is executed with real uid 0, and the command sanitiser is not a\nprivilege boundary: it admits `-v` with an arbitrary source, `--device`, `--cap-add`, `--security-opt`,\n`--user` and `--net`, and copies positional arguments through verbatim. A rewritten file therefore yields an\nattacker-authored, root-equivalent container invocation with the host filesystem available.\n\nFor the OCI path the same rewrite window applies, and mount validation is structural only, with no\nsource or destination allow-list, so arbitrary host paths can be bind-mounted read-write into the\ncontainer. The `username` field of the command file is likewise attacker-settable and is checked only\nagainst non-root and minimum-uid rules, permitting execution as another tenant's uid.\n\nMitigation\n\nUpgrade to 3.1.0, where the command file is validated before the ownership change and re-verified on open,\nand where mount sources and destinations are constrained by configuration.\n\nUsers who cannot upgrade immediately should disable Docker and OCI worker isolation, or restrict topology\nsubmission on affected supervisors to trusted principals. Note that the launcher must be rebuilt and\nreinstalled after upgrading.\n\nCredit\n\nThe ASF -- found using Claude agents to study the security of open-source projects, validated and reported by Apache Storm.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Apache Storm Worker Launcher: Local Privilege Escalation to Root via Container Command Files Chowned to the Tenant","id":"CVE-2026-82430","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Storm Client: Authorization Bypass When nimbus.groups Is Configured Without nimbus.users","id":"CVE-2026-82431"},"packages":[],"prev":{"headline":"Apache Storm Worker Launcher: Local Privilege Escalation to Root via a Time-of-Check Race in the Worker Launcher","id":"CVE-2026-82429"},"products":["Apache Storm Worker Launcher"],"published":"2026-09-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["Apache Software Foundation"]},"summary":"A race condition in Apache Storm's worker launcher allows local attackers to escalate privileges to root by modifying command files during container startup.","url":"https://insights.sbomify.com/CVE-2026-82430/"}
