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-2026-84828 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-2026-84828/ (Markdown: https://insights.sbomify.com/CVE-2026-84828/index.md)","id":"CVE-2026-84828","markdown":"https://insights.sbomify.com/CVE-2026-84828/index.md","name":"CVE-2026-84828","record":{"aliases":["DEBIAN-CVE-2026-84828","GHSA-5g5g-4cqv-r2jw","UBUNTU-CVE-2026-84828"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Pacemaker Configuration System","requires_auth":"low_privilege","summary":"Local attackers in the haclient group can read arbitrary short files via the pcs host auth command, exposing sensitive data like API keys.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"A flaw was found in PCS (Pacemaker Configuration System). A local attacker with membership in the 'haclient' group can exploit the 'pcs host auth --token' command to read the contents of arbitrary files on the filesystem, provided the files are shorter than 256 bytes. The file contents are read with root privileges by the pcsd daemon and can be exfiltrated by the attacker through subsequent cluster node communication. This allows disclosure of sensitive data such as API keys, tokens, or configuration secrets that would otherwise be inaccessible to the attacker.","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":"Pcs: pcs: non-root haclient users can read arbitrary files via pcs host auth --token","id":"CVE-2026-84828","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Optimole \u003c 4.2.12 - Unauthenticated Stored XSS via Srcset Descriptor Parameter","id":"CVE-2026-84829"},"packages":[],"prev":{"headline":"Org.wildfly.core: wildfly: path traversal in take-snapshot discloses the server configuration to the monitor role","id":"CVE-2026-84823"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat OpenShift Container Platform 4","Red Hat OpenStack Platform 16.2","Red Hat OpenStack Platform 17.1"],"published":"2026-09-10","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":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["Red Hat"]},"summary":"Local attackers in the haclient group can read arbitrary short files via the pcs host auth command, exposing sensitive data like API keys.","url":"https://insights.sbomify.com/CVE-2026-84828/"}
