Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-57296 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:external-workspace-manager (Maven): affected all versions; fixed in 1.4.0\n- org.jenkins-ci.plugins:external-workspace-manager (Maven): affected all versions; fixed in 1.4.0\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-2026-57296/ (Markdown: https://insights.sbomify.com/CVE-2026-57296/index.md)","id":"CVE-2026-57296","markdown":"https://insights.sbomify.com/CVE-2026-57296/index.md","name":"CVE-2026-57296","record":{"aliases":["GHSA-hrmj-8fm9-cg8x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins plugin","requires_auth":"low_privilege","summary":"Attackers with configure permissions can read arbitrary files and potentially execute code via path traversal in the Jenkins External Workspace Manager Plugin.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Jenkins External Workspace Manager Plugin 1.3.2 and earlier does not reject path traversal sequences in the custom workspace path provided to the exwsAllocate Pipeline step, allowing attackers with Item/Configure permission to read arbitrary files on the Jenkins controller file system, which can lead to remote code execution.","ecosystems":["Maven"],"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":"Jenkins External Workspace Manager Plugin has a path traversal vulnerability","id":"CVE-2026-57296","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins Contrast Continuous Application Security Plugin has a missing permission check","id":"CVE-2026-57297"},"packages":[{"ecosystem":"Maven","fixed":["1.4.0"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:external-workspace-manager","purl":null,"source":"GHSA-hrmj-8fm9-cg8x"},{"ecosystem":"Maven","fixed":["1.4.0"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:external-workspace-manager","purl":"pkg:maven/org.jenkins-ci.plugins/external-workspace-manager","source":"GHSA-hrmj-8fm9-cg8x"}],"prev":{"headline":"Jenkins EC2 Fleet Plugin has a cross-site request forgery (CSRF) vulnerability","id":"CVE-2026-57295"},"products":["Jenkins External Workspace Manager Plugin"],"published":"2026-06-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-06-24","vendors":["Jenkins Project"]},"summary":"Attackers with configure permissions can read arbitrary files and potentially execute code via path traversal in the Jenkins External Workspace Manager Plugin.","url":"https://insights.sbomify.com/CVE-2026-57296/"}
