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-2020-2226 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:matrix-auth (Maven): affected all versions; fixed in 2.6.2\n- org.jenkins-ci.plugins:matrix-auth (Maven): affected all versions; fixed in 2.6.2\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-2020-2226/ (Markdown: https://insights.sbomify.com/CVE-2020-2226/index.md)","id":"CVE-2020-2226","markdown":"https://insights.sbomify.com/CVE-2020-2226/index.md","name":"CVE-2020-2226","record":{"aliases":["GHSA-vr6v-wjfw-rxcr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins authorization plugin","requires_auth":"low_privilege","summary":"Stored cross-site scripting in Jenkins Matrix Authorization Strategy Plugin allows attackers to execute arbitrary scripts in victim browsers via unescaped user names.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"matrix_authorization_strategy","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 Matrix Authorization Strategy Plugin 2.6.1 and earlier does not escape user names shown in the configuration, resulting in a stored cross-site scripting vulnerability.","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 Matrix Authorization Strategy Plugin","id":"CVE-2020-2226","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in Jenkins Deployer Framework Plugin","id":"CVE-2020-2227"},"packages":[{"ecosystem":"Maven","fixed":["2.6.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:matrix-auth","purl":null,"source":"GHSA-vr6v-wjfw-rxcr"},{"ecosystem":"Maven","fixed":["2.6.2"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:matrix-auth","purl":"pkg:maven/org.jenkins-ci.plugins/matrix-auth","source":"GHSA-vr6v-wjfw-rxcr"}],"prev":{"headline":"Stored XSS vulnerability in multiple axis builds tooltips in Jenkins Matrix Project Plugin","id":"CVE-2020-2225"},"products":["Jenkins Matrix Authorization Strategy Plugin"],"published":"2020-07-15","related":[{"cvss_score":6.5,"headline":"Jenkins Matrix Authorization Strategy Plugin: Unsafe deserialization allows invocation of parameterless constructors","id":"CVE-2026-42521","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":6.5,"headline":"Incorrect permission checks in Jenkins Matrix Authorization Strategy Plugin may allow accessing some items","id":"CVE-2021-21623","kev_date_added":null,"published":"2021-03-18"}],"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":"2024-08-04","vendors":["Jenkins project"]},"summary":"Stored cross-site scripting in Jenkins Matrix Authorization Strategy Plugin allows attackers to execute arbitrary scripts in victim browsers via unescaped user names.","url":"https://insights.sbomify.com/CVE-2020-2226/"}
