Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-21630 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:extra-columns (Maven): affected all versions; fixed in 1.23\n- org.jenkins-ci.plugins:extra-columns (Maven): affected all versions; fixed in 1.23\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-2021-21630/ (Markdown: https://insights.sbomify.com/CVE-2021-21630/index.md)","id":"CVE-2021-21630","markdown":"https://insights.sbomify.com/CVE-2021-21630/index.md","name":"CVE-2021-21630","record":{"aliases":["GHSA-wx66-pm7r-2q82"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins plugin","requires_auth":"low_privilege","summary":"Stored XSS in Jenkins Extra Columns Plugin allows attackers with Job/Configure permission to execute scripts in other users' browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"extra_columns","vendor":"jenkins"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Jenkins Extra Columns Plugin 1.22 and earlier does not escape parameter values in the build parameters column, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.","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":"Stored XSS vulnerability in Jenkins Extra Columns Plugin","id":"CVE-2021-21630","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Missing permission check in Jenkins Cloud Statistics Plugin","id":"CVE-2021-21631"},"packages":[{"ecosystem":"Maven","fixed":["1.23"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:extra-columns","purl":null,"source":"GHSA-wx66-pm7r-2q82"},{"ecosystem":"Maven","fixed":["1.23"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:extra-columns","purl":"pkg:maven/org.jenkins-ci.plugins/extra-columns","source":"GHSA-wx66-pm7r-2q82"}],"prev":{"headline":"CSRF vulnerability in Jenkins Build With Parameters Plugin","id":"CVE-2021-21629"},"products":["Jenkins Extra Columns Plugin"],"published":"2021-03-30","related":[{"cvss_score":5.4,"headline":"Jenkins Extra Columns Plugin allows Cross-Site Scripting (XSS)","id":"CVE-2016-3101","kev_date_added":null,"published":"2017-02-09"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Jenkins project"]},"summary":"Stored XSS in Jenkins Extra Columns Plugin allows attackers with Job/Configure permission to execute scripts in other users' browsers.","url":"https://insights.sbomify.com/CVE-2021-21630/"}
