An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-34486 in the wild since at least 4 Aug 2026.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.53; fixed in 10.1.54\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.53; fixed in 10.1.54\n- org.apache.tomcat:tomcat (Maven): affected from 11.0.20; fixed in 11.0.21\n- org.apache.tomcat:tomcat (Maven): affected from 11.0.20; fixed in 11.0.21\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.116; fixed in 9.0.117\n- org.apache.tomcat:tomcat (Maven): affected from 9.0.116; fixed in 9.0.117\n- tomcat (Bitnami): affected from 9.0.116; fixed in 9.0.117, 10.1.54, 11.0.21\n- org.apache.tomcat:tomcat-tribes (Maven): affected from 10.1.53; fixed in 10.1.54\n- org.apache.tomcat:tomcat-tribes (Maven): affected from 10.1.53; fixed in 10.1.54\n- org.apache.tomcat:tomcat-tribes (Maven): affected from 11.0.20; fixed in 11.0.21\n- org.apache.tomcat:tomcat-tribes (Maven): affected from 11.0.20; fixed in 11.0.21\n- org.apache.tomcat:tomcat-tribes (Maven): affected from 9.0.116; fixed in 9.0.117\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-2026-34486/ (Markdown: https://insights.sbomify.com/CVE-2026-34486/index.md)","id":"CVE-2026-34486","markdown":"https://insights.sbomify.com/CVE-2026-34486/index.md","name":"CVE-2026-34486","record":{"aliases":["BIT-tomcat-2026-34486","CLSA-2026-1786391661","GHSA-69r9-qgr7-g2wj","ROOT-APP-MAVEN-CVE-2026-34486","UBUNTU-CVE-2026-34486"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can bypass the EncryptInterceptor in Apache Tomcat, potentially exposing sensitive data if encryption is enabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_els","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_tus","vendor":"redhat"},{"product":"enterprise_linux_update_services_for_sap_solutions","vendor":"redhat"},{"product":"jboss_web_server","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-807","name":"Reliance on Untrusted Inputs in a Security Decision"},{"id":"CWE-311","name":"Missing Encryption of Sensitive Data"}],"description":"Missing Encryption of Sensitive Data vulnerability in Apache Tomcat due to the fix for CVE-2026-29146 allowing the bypass of the EncryptInterceptor.\n\nThis issue affects Apache Tomcat: 11.0.20, 10.1.53, 9.0.116.\n\nUsers are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117, which fix the issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-04-15","github_poc":5,"max_poc_stars":70,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-05-11T14:07:46Z","kind":"github_poc","ref":"https://github.com/striga-ai/CVE-2026-34486","stars":70,"title":"EncryptInterceptor fail-open bypass in Apache Tomcat Tribes clustering leading to unauthenticated RCE via Java deserialization."},{"date":"2026-04-15T07:30:15Z","kind":"github_poc","ref":"https://github.com/AirSkye/CVE-2026-34486-poc","stars":12,"title":"CVE-2026-34486 Apache Tomcat EncryptInterceptor 绕过漏洞复现（使用GLM5.1复现完成）"},{"date":"2026-04-15T13:55:55Z","kind":"github_poc","ref":"https://github.com/404-src/CVE-2026-34486","stars":10,"title":"Apache Tomcat EncryptInterceptor Bypass → Unauthenticated RCE (CVE-2026-34486)"},{"date":"2026-07-23T03:46:21Z","kind":"github_poc","ref":"https://github.com/razureink/cve-2026-34486-tomcat_encrypt_bypass_reproduction","stars":0,"title":"CVE Reproduction: cve-2026-34486-tomcat_encrypt_bypass_reproduction"},{"date":"2026-08-19T00:39:18Z","kind":"github_poc","ref":"https://github.com/CypherHippie/CVE-2026-34486---unauthenticated-RCE-via-Java-deserialization","stars":0,"title":"EncryptInterceptor fail-open bypass in Apache Tomcat Tribes clustering leading to unauthenticated RCE via Java deserialization."},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-34486.yaml","stars":null,"title":"Apache Tomcat Tribes EncryptInterceptor Bypass - Remote Code Execution"}],"tier":"exploited"},"has_fix":true,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","indexable":true,"kev":{"dateAdded":"2026-08-04","dueDate":"2026-08-07","knownRansomwareCampaignUse":"Unknown","product":"Tomcat","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
