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-2026-57289 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.jenkins.plugins:bitbucket-push-and-pull-request (Maven): affected all versions; fixed in 3.3.9\n- io.jenkins.plugins:bitbucket-push-and-pull-request (Maven): affected all versions; fixed in 3.3.9\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-2026-57289/ (Markdown: https://insights.sbomify.com/CVE-2026-57289/index.md)","id":"CVE-2026-57289","markdown":"https://insights.sbomify.com/CVE-2026-57289/index.md","name":"CVE-2026-57289","record":{"aliases":["GHSA-jwhr-h7pc-3974"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Bitbucket plugin","requires_auth":"none","summary":"Attackers can intercept network traffic to capture Bearer tokens due to disabled SSL/TLS validation in the Jenkins Bitbucket plugin.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"bitbucket_push_and_pull_request","vendor":"jenkins"}],"cvss":{"score":4.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Jenkins Bitbucket Push and Pull Request Plugin 3.3.8 and earlier unconditionally disables SSL/TLS certificate and hostname validation for connections sending Bearer token authenticated requests to the configured Bitbucket Server endpoint, allowing attackers able to intercept network traffic to capture the token.","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 Bitbucket Push and Pull Request Plugin unconditionally disables SSL/TLS certificate validation","id":"CVE-2026-57289","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins Priority Sorter Plugin has a CSRF vulnerability","id":"CVE-2026-57290"},"packages":[{"ecosystem":"Maven","fixed":["3.3.9"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:bitbucket-push-and-pull-request","purl":null,"source":"GHSA-jwhr-h7pc-3974"},{"ecosystem":"Maven","fixed":["3.3.9"],"introduced":["0"],"last_affected":[],"package":"io.jenkins.plugins:bitbucket-push-and-pull-request","purl":"pkg:maven/io.jenkins.plugins/bitbucket-push-and-pull-request","source":"GHSA-jwhr-h7pc-3974"}],"prev":{"headline":"Jenkins Active Directory Plugin has an LDAP injection vulnerability","id":"CVE-2026-57288"},"products":["Jenkins Bitbucket Push and Pull Request Plugin"],"published":"2026-06-24","related":[{"cvss_score":7.5,"headline":"SSRF vulnerability in Jenkins Bitbucket Push and Pull Request Plugin allows capturing credentials","id":"CVE-2023-41937","kev_date_added":null,"published":"2023-09-06"}],"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 can intercept network traffic to capture Bearer tokens due to disabled SSL/TLS validation in the Jenkins Bitbucket plugin.","url":"https://insights.sbomify.com/CVE-2026-57289/"}
