Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48921 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.jenkins.plugins:pipeline-groovy-lib (Maven): affected all versions; fixed in 798.v5cc688825312\n- io.jenkins.plugins:pipeline-groovy-lib (Maven): affected all versions; fixed in 798.v5cc688825312\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-2026-48921/ (Markdown: https://insights.sbomify.com/CVE-2026-48921/index.md)","id":"CVE-2026-48921","markdown":"https://insights.sbomify.com/CVE-2026-48921/index.md","name":"CVE-2026-48921","record":{"aliases":["GHSA-qjq3-wqj5-g37q"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Groovy Libraries Plugin","requires_auth":"low_privilege","summary":"Attackers controlling shared library content can use symbolic links to read arbitrary files on the Jenkins controller filesystem.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"pipeline\\","vendor":"jenkins"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Jenkins Pipeline: Groovy Libraries Plugin 797.v90ea_a_9b_e45a_0 and earlier does not prohibit symbolic links in shared libraries, allowing attackers able to control the content of a library used by a Pipeline job to read arbitrary files on the Jenkins controller filesystem.","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 Pipeline: Groovy Libraries Plugin does not prohibit symbolic links in shared libraries","id":"CVE-2026-48921","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 Credentials Binding Plugin does not properly sanitize file names for file and zip file credentials","id":"CVE-2026-48922"},"packages":[{"ecosystem":"Maven","fixed":["798.v5cc688825312"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:pipeline-groovy-lib","purl":null,"source":"GHSA-qjq3-wqj5-g37q"},{"ecosystem":"Maven","fixed":["798.v5cc688825312"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:pipeline-groovy-lib","purl":"pkg:maven/io.jenkins.plugins/pipeline-groovy-lib","source":"GHSA-qjq3-wqj5-g37q"}],"prev":{"headline":"Jenkins Email Extension Plugin: Attackers able to control email content may specify `file:` URLs for images to read arbitrary files from Jenkins controller filesystem","id":"CVE-2026-48920"},"products":["Jenkins Pipeline: Groovy Libraries Plugin"],"published":"2026-05-27","related":[{"cvss_score":9.9,"headline":"Jenkins Matrix Project Plugin Remote Code Execution","id":"CVE-2019-1003030","kev_date_added":"2022-03-25","published":"2019-03-08"},{"cvss_score":9.9,"headline":"Jenkins Pipeline: Groovy Plugin allows sandbox protection bypass and arbitrary code execution","id":"CVE-2022-43402","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":9.8,"headline":"Sandbox bypass vulnerability in Jenkins Pipeline: Groovy Plugin","id":"CVE-2019-1003041","kev_date_added":null,"published":"2019-03-28"},{"cvss_score":8.8,"headline":"CSRF protection for any URL can be bypassed in Jenkins Pipeline: Input Step Plugin","id":"CVE-2022-43407","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":8.8,"headline":"Improper Neutralization of Special Elements used in an OS Command in Jenkins Pipeline: Groovy Plugin","id":"CVE-2022-25173","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":8.8,"headline":"Improper Neutralization of Special Elements used in an OS Command in Jenkins Pipeline: Shared Groovy Libraries Plugin","id":"CVE-2022-25174","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":8.8,"headline":"Jenkins Pipeline: Multibranch Plugin vulnerable to OS Command Injection","id":"CVE-2022-25175","kev_date_added":null,"published":"2022-02-15"}],"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":"US public information, NVD API terms","name":"NVD"},{"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":"2026-05-27","vendors":["Jenkins Project"]},"summary":"Attackers controlling shared library content can use symbolic links to read arbitrary files on the Jenkins controller filesystem.","url":"https://insights.sbomify.com/CVE-2026-48921/"}
