Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21676 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:requests (Maven): affected all versions; fixed in 2.2.8\n- org.jenkins-ci.plugins:requests (Maven): affected all versions; fixed in 2.2.8\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-2021-21676/ (Markdown: https://insights.sbomify.com/CVE-2021-21676/index.md)","id":"CVE-2021-21676","markdown":"https://insights.sbomify.com/CVE-2021-21676/index.md","name":"CVE-2021-21676","record":{"aliases":["GHSA-w3gm-vv58-wr55"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins requests-plugin","requires_auth":"low_privilege","summary":"Attackers with read permissions can send test emails to arbitrary addresses due to missing permission checks in the Jenkins requests-plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"requests","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Jenkins requests-plugin Plugin 2.2.7 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to send test emails to an attacker-specified email address.","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":"Missing permission check in Jenkins requests-plugin Plugin allows sending emails","id":"CVE-2021-21676","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"RCE vulnerability in Jenkins Code Coverage API Plugin","id":"CVE-2021-21677"},"packages":[{"ecosystem":"Maven","fixed":["2.2.8"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:requests","purl":null,"source":"GHSA-w3gm-vv58-wr55"},{"ecosystem":"Maven","fixed":["2.2.8"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:requests","purl":"pkg:maven/org.jenkins-ci.plugins/requests","source":"GHSA-w3gm-vv58-wr55"}],"prev":{"headline":"CSRF vulnerabilities in Jenkins requests-plugin Plugin","id":"CVE-2021-21675"},"products":["Jenkins requests-plugin Plugin"],"published":"2021-06-30","related":[{"cvss_score":6.5,"headline":"CSRF vulnerabilities in Jenkins requests-plugin Plugin","id":"CVE-2021-21675","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":4.3,"headline":"Incorrect Authorization in Jenkins requests-plugin","id":"CVE-2022-34782","kev_date_added":null,"published":"2022-06-30"},{"cvss_score":4.3,"headline":"Missing permission check in Jenkins requests-plugin Plugin allows viewing pending requests","id":"CVE-2021-21674","kev_date_added":null,"published":"2021-06-30"}],"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":"Attackers with read permissions can send test emails to arbitrary addresses due to missing permission checks in the Jenkins requests-plugin.","url":"https://insights.sbomify.com/CVE-2021-21676/"}
