It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15688 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation GX Works3. 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-2026-15688/ (Markdown: https://insights.sbomify.com/CVE-2026-15688/index.md)","id":"CVE-2026-15688","markdown":"https://insights.sbomify.com/CVE-2026-15688/index.md","name":"CVE-2026-15688","record":{"aliases":["GHSA-x4hf-m6gp-2m3x"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mitsubishi PLC software","requires_auth":"low_privilege","summary":"A local attacker can bypass block password authentication in Mitsubishi GX Works3 by modifying memory, allowing unauthorized access to control programs.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"description":"Incorrect Implementation of Authentication Algorithm Vulnerability in Mitsubishi Electric GX Works3 and Motion Control Setting allows a local attacker to successfully authenticate even with an invalid block password by executing the affected product and modifying part of the executable module in memory, and thereby may be able to view, tamper with, destroy, or delete control programs.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Password Authentication Bypass Vulnerability in GX Works3 and Motion Control Setting","id":"CVE-2026-15688","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Open redirect in Dancer2::Plugin::Auth::Extensible","id":"CVE-2026-15689"},"packages":[],"prev":{"headline":"Path traversal via non-tar copyDirectoryFromPod","id":"CVE-2026-15687"},"products":["GX Works3","Motion Control Setting"],"published":"2026-09-17","related":[],"sources":[{"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":"2026-10-09","vendors":["Mitsubishi Electric Corporation"]},"summary":"A local attacker can bypass block password authentication in Mitsubishi GX Works3 by modifying memory, allowing unauthorized access to control programs.","url":"https://insights.sbomify.com/CVE-2026-15688/"}
