Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42522 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:github-branch-source (Maven): affected all versions; fixed in 1967.1969.v205fd594c821\n- org.jenkins-ci.plugins:github-branch-source (Maven): affected all versions; fixed in 1967.1969.v205fd594c821\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-2026-42522/ (Markdown: https://insights.sbomify.com/CVE-2026-42522/index.md)","id":"CVE-2026-42522","markdown":"https://insights.sbomify.com/CVE-2026-42522/index.md","name":"CVE-2026-42522","record":{"aliases":["GHSA-wg26-8wmj-cf9p"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins GitHub Branch Source Plugin","requires_auth":"low_privilege","summary":"Attackers with read access can connect to arbitrary URLs using GitHub App credentials due to missing permission checks in the Jenkins plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"github_branch_source","vendor":"jenkins"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","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":"A missing permission check in Jenkins GitHub Branch Source Plugin 1967.vdea_d580c1a_b_a_ and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL with attacker-specified GitHub App credentials.","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 GitHub Branch Source Plugin: Missing permissions check allows attackers to perform a connection test","id":"CVE-2026-42522","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 GitHub Plugin has an XSS vulnerability","id":"CVE-2026-42523"},"packages":[{"ecosystem":"Maven","fixed":["1967.1969.v205fd594c821"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:github-branch-source","purl":null,"source":"GHSA-wg26-8wmj-cf9p"},{"ecosystem":"Maven","fixed":["1967.1969.v205fd594c821"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:github-branch-source","purl":"pkg:maven/org.jenkins-ci.plugins/github-branch-source","source":"GHSA-wg26-8wmj-cf9p"}],"prev":{"headline":"Jenkins Matrix Authorization Strategy Plugin: Unsafe deserialization allows invocation of parameterless constructors","id":"CVE-2026-42521"},"products":["Jenkins GitHub Branch Source Plugin"],"published":"2026-04-29","related":[{"cvss_score":6.5,"headline":"Shared projects are unconditionally discovered by Jenkins GitLab Branch Source Plugin","id":"CVE-2024-23901","kev_date_added":null,"published":"2024-01-24"},{"cvss_score":6.3,"headline":"Jenkins GitHub Branch Source Plugin vulnerable to Cross-Site Request Forgery","id":"CVE-2017-1000091","kev_date_added":null,"published":"2017-10-04"},{"cvss_score":5.3,"headline":"Non-constant time webhook token comparison in Jenkins GitLab Branch Source Plugin","id":"CVE-2024-23903","kev_date_added":null,"published":"2024-01-24"},{"cvss_score":4.3,"headline":"Jenkins GitHub Branch Source Plugin has missing permission check that allows enumerating GitHub Enterprise server URLs","id":"CVE-2026-57285","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":4.3,"headline":"CSRF vulnerability in Jenkins GitLab Branch Source Plugin","id":"CVE-2024-23902","kev_date_added":null,"published":"2024-01-24"},{"cvss_score":4.3,"headline":"Jenkins GitHub Branch Source Plugin vulnerable to Server-Side Request Forgery","id":"CVE-2018-1000185","kev_date_added":null,"published":"2018-06-05"}],"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":"2026-04-29","vendors":["Jenkins Project"]},"summary":"Attackers with read access can connect to arbitrary URLs using GitHub App credentials due to missing permission checks in the Jenkins plugin.","url":"https://insights.sbomify.com/CVE-2026-42522/"}
