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-2026-70426 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jenkins (Bitnami): affected all versions; fixed in 2.568.2, 2.576.0\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-2026-70426/ (Markdown: https://insights.sbomify.com/CVE-2026-70426/index.md)","id":"CVE-2026-70426","markdown":"https://insights.sbomify.com/CVE-2026-70426/index.md","name":"CVE-2026-70426","record":{"aliases":["BIT-jenkins-2026-70426","GHSA-v269-8r2r-vj93","MINI-32q3-hp89-j69x","MINI-4274-4mr9-4vv7","MINI-47x5-49xh-w8m4","MINI-cwpc-pwgj-753f","MINI-gmvq-6w36-f8hv","MINI-m972-rf26-4pcp","MINI-qrgh-h45f-mhv6","MINI-w8j2-qqj8-7r9j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins automation server","requires_auth":"none","summary":"Attackers with agent access can bypass deserialization filters to execute arbitrary code on the Jenkins controller.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[],"cvss":{"score":9,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"In Remoting 3384.v60d89463d9e0 and earlier, except 3355.3357.v931d3c992987, included in Jenkins 2.575 and earlier, LTS 2.568.1 and earlier, the JEP-200 class filter is not applied to classes resolved via a fallback path in the Remoting deserialization implementation, allowing agent processes, code running on agents, and attackers with Agent/Connect permission to bypass the JEP-200 deserialization filter for classes on the Jenkins core classpath.","ecosystems":["Bitnami"],"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":"Deserialization in Jenkins","id":"CVE-2026-70426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Path traversal in Jenkins","id":"CVE-2026-70427"},"packages":[{"ecosystem":"Bitnami","fixed":["2.568.2","2.576.0"],"introduced":["0","2.569.0"],"last_affected":[],"package":"jenkins","purl":"pkg:bitnami/jenkins","source":"BIT-jenkins-2026-70426"}],"prev":{"headline":"Command injection in PowerScale OneFS","id":"CVE-2026-70425"},"products":["Jenkins","Remoting"],"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2026-08-06","vendors":["Jenkins Project"]},"summary":"Attackers with agent access can bypass deserialization filters to execute arbitrary code on the Jenkins controller.","url":"https://insights.sbomify.com/CVE-2026-70426/"}
