Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-57294 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.amazon.jenkins.fleet:ec2-fleet (Maven): affected all versions; fixed in 4.2.3.540.va\n- com.amazon.jenkins.fleet:ec2-fleet (Maven): affected all versions; fixed in 4.2.3.540.va\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-2026-57294/ (Markdown: https://insights.sbomify.com/CVE-2026-57294/index.md)","id":"CVE-2026-57294","markdown":"https://insights.sbomify.com/CVE-2026-57294/index.md","name":"CVE-2026-57294","record":{"aliases":["GHSA-9v77-j4xv-34gq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins EC2 Fleet Plugin","requires_auth":"low_privilege","summary":"Attackers with read permissions can capture AWS credentials by connecting to a malicious URL due to missing permission checks in the Jenkins EC2 Fleet Plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"ec2_fleet","vendor":"jenkins"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins EC2 Fleet Plugin 4.2.3.539.v8fedff2a_81c3 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing AWS credentials stored in Jenkins.","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 EC2 Fleet Plugin has a missing permission check","id":"CVE-2026-57294","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins EC2 Fleet Plugin has a cross-site request forgery (CSRF) vulnerability","id":"CVE-2026-57295"},"packages":[{"ecosystem":"Maven","fixed":["4.2.3.540.va"],"introduced":["0"],"last_affected":[],"package":"com.amazon.jenkins.fleet:ec2-fleet","purl":null,"source":"GHSA-9v77-j4xv-34gq"},{"ecosystem":"Maven","fixed":["4.2.3.540.va"],"introduced":["0"],"last_affected":[],"package":"com.amazon.jenkins.fleet:ec2-fleet","purl":"pkg:maven/com.amazon.jenkins.fleet/ec2-fleet","source":"GHSA-9v77-j4xv-34gq"}],"prev":{"headline":"Jenkins Gitee Plugin has an incorrect permission check that allows enumerating credentials IDs","id":"CVE-2026-57293"},"products":["Jenkins EC2 Fleet Plugin"],"published":"2026-06-24","related":[{"cvss_score":5.4,"headline":"Jenkins EC2 Fleet Plugin has a cross-site request forgery (CSRF) vulnerability","id":"CVE-2026-57295","kev_date_added":null,"published":"2026-06-24"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-06-24","vendors":["Jenkins Project"]},"summary":"Attackers with read permissions can capture AWS credentials by connecting to a malicious URL due to missing permission checks in the Jenkins EC2 Fleet Plugin.","url":"https://insights.sbomify.com/CVE-2026-57294/"}
