It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-34926 in the wild since at least 21 May 2026.\n\nAffected product: Trendmicro Apex One. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-34926/ (Markdown: https://insights.sbomify.com/CVE-2026-34926/index.md)","id":"CVE-2026-34926","markdown":"https://insights.sbomify.com/CVE-2026-34926/index.md","name":"CVE-2026-34926","record":{"aliases":["GHSA-4ccp-cqrh-3w9v"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Trend Micro Apex One","requires_auth":"high_privilege","summary":"A local attacker with administrative credentials can exploit a directory traversal flaw in the on-premise Apex One server to inject malicious code deployed to agents.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trendmicro","cpe":[{"product":"apex_one","vendor":"trendmicro"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"A directory traversal vulnerability in the Apex One (on-premise) server could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations.\n\n\r\nThis vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must have access to the Apex One Server and already obtained administrative credentials to the server via some other method to exploit this vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-05-22","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-05-22T09:58:04Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-34926","stars":0,"title":"CVE-2026-34926"}],"tier":"exploited"},"has_fix":null,"headline":"Trend Micro Apex One (On-Premise) Directory Traversal","id":"CVE-2026-34926","indexable":true,"kev":{"dateAdded":"2026-05-21","dueDate":"2026-06-04","knownRansomwareCampaignUse":"Unknown","product":"Apex One","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"Trend Micro","vulnerabilityName":"Trend Micro Apex One (On-Premise) Directory Traversal Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"trendmicro:apex_one","products":["trendmicro:apex_one"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Privilege escalation in TrendAI Apex One","id":"CVE-2026-34927"},"packages":[],"prev":{"headline":"Auth bypass in Adserver","id":"CVE-2026-34917"},"products":["TrendAI Apex One","TrendAI Apex One as a Service"],"published":"2026-05-21","related":[{"cvss_score":9.8,"headline":"Trend Micro Apex One and OfficeScan Authentication Bypass","id":"CVE-2020-8599","kev_date_added":"2021-11-03","published":"2020-03-18"},{"cvss_score":9.4,"headline":"Trend Micro Apex One OS Command Injection","id":"CVE-2025-54948","kev_date_added":"2025-08-18","published":"2025-08-05"},{"cvss_score":8.8,"headline":"Trend Micro Multiple Products Improper Input Validation","id":"CVE-2021-36741","kev_date_added":"2021-11-03","published":"2021-07-29"},{"cvss_score":8.8,"headline":"Trend Micro Apex One and OfficeScan Remote Code Execution","id":"CVE-2020-8467","kev_date_added":"2021-11-03","published":"2020-03-18"},{"cvss_score":8.8,"headline":"Trend Micro Multiple Products Content Validation Escape","id":"CVE-2020-8468","kev_date_added":"2021-11-03","published":"2020-03-18"},{"cvss_score":7.8,"headline":"Trend Micro Multiple Products Improper Input Validation","id":"CVE-2021-36742","kev_date_added":"2021-11-03","published":"2021-07-29"},{"cvss_score":7.8,"headline":"Trend Micro Multiple Products Improper Access Control","id":"CVE-2020-24557","kev_date_added":"2021-11-03","published":"2020-09-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["Trend Micro, Inc."]},"summary":"A local attacker with administrative credentials can exploit a directory traversal flaw in the on-premise Apex One server to inject malicious code deployed to agents.","url":"https://insights.sbomify.com/CVE-2026-34926/"}
