Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2261 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.jenkins.plugins:perfecto (Maven): affected all versions; fixed in 1.18\n- io.jenkins.plugins:perfecto (Maven): affected all versions; fixed in 1.18\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-2020-2261/ (Markdown: https://insights.sbomify.com/CVE-2020-2261/index.md)","id":"CVE-2020-2261","markdown":"https://insights.sbomify.com/CVE-2020-2261/index.md","name":"CVE-2020-2261","record":{"aliases":["GHSA-jq84-6fmm-6qv6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Perfecto Plugin","requires_auth":"low_privilege","summary":"Attackers with Job/Configure permission can execute arbitrary commands on the Jenkins controller via the Perfecto Plugin.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"perfecto","vendor":"jenkins"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Jenkins Perfecto Plugin 1.17 and earlier executes a command on the Jenkins controller, allowing attackers with Job/Configure permission to run arbitrary commands on the Jenkins controller","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2025-08-16","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-16T11:58:24Z","kind":"github_poc","ref":"https://github.com/shoucheng3/jenkinsci__perfecto-plugin_CVE-2020-2261_1-17","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"OS command execution vulnerability in Perfecto Plugin","id":"CVE-2020-2261","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Stored XSS vulnerability in android-lint Plugin","id":"CVE-2020-2262"},"packages":[{"ecosystem":"Maven","fixed":["1.18"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:perfecto","purl":null,"source":"GHSA-jq84-6fmm-6qv6"},{"ecosystem":"Maven","fixed":["1.18"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:perfecto","purl":"pkg:maven/io.jenkins.plugins/perfecto","source":"GHSA-jq84-6fmm-6qv6"}],"prev":{"headline":"Missing permission check in Perfecto Plugin","id":"CVE-2020-2260"},"products":["Jenkins Perfecto Plugin"],"published":"2020-09-16","related":[{"cvss_score":4.3,"headline":"Missing permission check in Perfecto Plugin","id":"CVE-2020-2260","kev_date_added":null,"published":"2020-09-16"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Jenkins project"]},"summary":"Attackers with Job/Configure permission can execute arbitrary commands on the Jenkins controller via the Perfecto Plugin.","url":"https://insights.sbomify.com/CVE-2020-2261/"}
