An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-30521 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:assembla-merge-request-builder (Maven): affected all versions up to 1.1.13; no fix listed\n- org.jenkins-ci.plugins:assembla-merge-request-builder (Maven): affected all versions up to 1.1.13; no fix listed\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-2023-30521/ (Markdown: https://insights.sbomify.com/CVE-2023-30521/index.md)","id":"CVE-2023-30521","markdown":"https://insights.sbomify.com/CVE-2023-30521/index.md","name":"CVE-2023-30521","record":{"aliases":["GHSA-jr86-6j4j-mv45"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins plugin","requires_auth":"none","summary":"Unauthenticated attackers can trigger builds for specified repositories due to a missing permission check in the Jenkins Assembla merge request builder plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"assembla_merge_request_builder","vendor":"jenkins"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins Assembla merge request builder Plugin 1.1.13 and earlier allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified repository.","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":false,"headline":"Jenkins Assembla merge request builder Plugin missing authentication to access endpoint","id":"CVE-2023-30521","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":2,"n_references":2,"next":{"headline":"Jenkins Fogbugz Plugin has missing permissions check","id":"CVE-2023-30522"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.1.13"],"package":"org.jenkins-ci.plugins:assembla-merge-request-builder","purl":null,"source":"GHSA-jr86-6j4j-mv45"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.1.13"],"package":"org.jenkins-ci.plugins:assembla-merge-request-builder","purl":"pkg:maven/org.jenkins-ci.plugins/assembla-merge-request-builder","source":"GHSA-jr86-6j4j-mv45"}],"prev":{"headline":"Jenkins Quay.io trigger Plugin Cross-site Scripting vulnerability","id":"CVE-2023-30520"},"products":["Jenkins Assembla merge request builder Plugin"],"published":"2023-04-12","related":[],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-07","vendors":["Jenkins Project"]},"summary":"Unauthenticated attackers can trigger builds for specified repositories due to a missing permission check in the Jenkins Assembla merge request builder plugin.","url":"https://insights.sbomify.com/CVE-2023-30521/"}
