Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-70436 in the wild and no public exploit code.\n\nAffected product: Jenkins External Workspace Manager Plugin. 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-2026-70436/ (Markdown: https://insights.sbomify.com/CVE-2026-70436/index.md)","id":"CVE-2026-70436","markdown":"https://insights.sbomify.com/CVE-2026-70436/index.md","name":"CVE-2026-70436","record":{"aliases":["GHSA-w8fh-xx7f-5j67"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins plugin","requires_auth":"low_privilege","summary":"Attackers with Overall/Read permission can read unauthorized workspace files due to missing or improper permission checks in the Jenkins External Workspace Manager Plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Jenkins External Workspace Manager Plugin 1.4.1 and earlier does not perform a permission check (1.4.0 and earlier) or performs an improper permission check (1.4.1) when providing access to externally-managed workspaces through the workspace browser, allowing attackers with Overall/Read permission to read files in workspaces they are not authorized to access.","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":"Missing authorization in Jenkins External Workspace Manager Plugin","id":"CVE-2026-70436","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Jenkins Webhook Secret Credentials Provider Plugin","id":"CVE-2026-70437"},"packages":[],"prev":{"headline":"Missing authorization in Jenkins SCM-Manager Plugin","id":"CVE-2026-70435"},"products":["Jenkins External Workspace Manager Plugin"],"published":"2026-08-05","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":"2026-08-06","vendors":["Jenkins Project"]},"summary":"Attackers with Overall/Read permission can read unauthorized workspace files due to missing or improper permission checks in the Jenkins External Workspace Manager Plugin.","url":"https://insights.sbomify.com/CVE-2026-70436/"}
