It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84838 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-84838/ (Markdown: https://insights.sbomify.com/CVE-2026-84838/index.md)","id":"CVE-2026-84838","markdown":"https://insights.sbomify.com/CVE-2026-84838/index.md","name":"CVE-2026-84838","record":{"aliases":["AZL-99372","DEBIAN-CVE-2026-84838","ECHO-f52f-43fd-e847","GHSA-h54x-hjr5-ww2x","UBUNTU-CVE-2026-84838"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"RHEL rpmuncompress utility","requires_auth":"none","summary":"Local attackers can execute arbitrary commands via crafted archive filenames in rpmuncompress, requiring user interaction to trigger.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A flaw was found in rpmuncompress. This command injection vulnerability allows a local attacker to execute arbitrary commands. This occurs when rpmuncompress processes a specially crafted archive filename containing shell metacharacters, which are not properly escaped before being passed to shell command strings. Successful exploitation requires user interaction, where a user or automated workflow invokes rpmuncompress on the malicious file, leading to high impact on the confidentiality, integrity, and availability of data accessible to the invoking user.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Rpm: command injection in rpmuncompress via unescaped filenames passed to popen()","id":"CVE-2026-84838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"tsi-coop tsi-dpdp-cms Admin Console/DPO Compliance Console web.xml missing authentication","id":"CVE-2026-84839"},"packages":[],"prev":{"headline":"Rpm: command injection in `rpmbuild -t*` (`gettarspec`) via unescaped tarball path","id":"CVE-2026-84837"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Hardened Images"],"published":"2026-09-02","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":"2026-10-14","vendors":["Red Hat"]},"summary":"Local attackers can execute arbitrary commands via crafted archive filenames in rpmuncompress, requiring user interaction to trigger.","url":"https://insights.sbomify.com/CVE-2026-84838/"}
