🔥 CyberForge CVE of the Day #018 🚨 CVE-2026-70426 — Jenkins Agent-to-Controller Deserialization Filter Bypass A critical flaw in Jenkins Remoting can let a compromised or attacker-controlled agent bypass the JEP-200 deserialization class filter and potentially execute code on the Jenkins controller. ⭐ CVSS: 9.0 Critical ⭐ CWE: CWE-502 — Deserialization of Untrusted Data ⭐ Privileges Required: None ⭐ User Interaction: None ⭐ Exploitation: None observed ⭐ Technical Impact: Total ⚠️ Why It Matters. Jenkins agents are intentionally less trusted than the controller. CVE-2026-70426 breaks part of that boundary because a fallback class-resolution path failed to apply JEP-200 filtering. A successful attack could expose: • Jenkins credentials and API tokens • cloud and deployment secrets • pipeline configuration • build artefacts • connected production infrastructure A controller compromise may become a software supply-chain incident. 🛡️ Affected / Fixed. Affected: • Jenkins 2.575 and earlier • LTS 2.568.1 and earlier Fixed: • Jenkins 2.576 • LTS 2.568.2 The Remoting fix also applies the JEP-200 filter to the fallback resolution path. 🔍 Detection: Watch for unusual agent reconnects, suspicious Agent/Connect activity, unexpected changes to JENKINS_HOME, and the Jenkins Java process spawning cmd.exe, PowerShell, sh, bash, curl or wget. 🔧 Remediation: Upgrade immediately and verify the corrected Remoting version. Disconnect suspicious agents, review Agent/Connect permissions, and rotate Jenkins/cloud/deployment credentials if controller compromise is suspected. 🔗 https://nvd.nist.gov/vuln/detail/CVE-2026-70426 #CyberForge #CVE202670426 #Jenkins #JenkinsSecurity #JEP200 #Deserialization #CICD #SupplyChain #BlueTeam

🚨Critical - Jenkins Remoting JEP-200 Deserialization Filter Bypass (CVE-2026-70426) In Jenkins Remoting, the JEP-200 class filter isn’t enforced for classes resolved via a fallback deserialization path, letting attacker-controlled agents bypass the filter for Jenkins core classpath classes. Exploitable by agent processes/code on agents or anyone with Agent/Connect to trigger unsafe deserialization and potentially RCE. 👉Affected: Jenkins Remoting <= 3384.v60d89463d9e0 (except 3355.3357.v931d3c992987); Jenkins <= 2.575 / LTS <= 2.568.1
