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-2026-23767 in the wild and no public exploit code.\n\nAffected product: Seiko Epson Corporation ESC/POS. 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-2026-23767/ (Markdown: https://insights.sbomify.com/CVE-2026-23767/index.md)","id":"CVE-2026-23767","markdown":"https://insights.sbomify.com/CVE-2026-23767/index.md","name":"CVE-2026-23767","record":{"aliases":["GHSA-57q8-p4r4-7xr7"],"analysis":{"component_type":"hardware_firmware","fix_type":"no_fix_stated","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ESC/POS printer protocol","requires_auth":"none","summary":"ESC/POS protocol lacks authentication and encryption, allowing attackers to execute arbitrary commands or modify data on compatible printers.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"sb-h50_firmware","vendor":"epson"},{"product":"tm-h6000v_firmware","vendor":"epson"},{"product":"tm-l100_firmware","vendor":"epson"},{"product":"tm-m10_firmware","vendor":"epson"},{"product":"tm-m30_firmware","vendor":"epson"},{"product":"tm-m30ii-h_firmware","vendor":"epson"},{"product":"tm-m30ii-s_firmware","vendor":"epson"},{"product":"tm-m30ii-sl_firmware","vendor":"epson"},{"product":"tm-m30ii_firmware","vendor":"epson"},{"product":"tm-m30iii-h_firmware","vendor":"epson"},{"product":"tm-m30iii_firmware","vendor":"epson"},{"product":"tm-m55_firmware","vendor":"epson"},{"product":"tm-p20_firmware","vendor":"epson"},{"product":"tm-p20ii_firmware","vendor":"epson"},{"product":"tm-p60ii_firmware","vendor":"epson"},{"product":"tm-p80_firmware","vendor":"epson"},{"product":"tm-p80ii_firmware","vendor":"epson"},{"product":"tm-t20ii_firmware","vendor":"epson"},{"product":"tm-t20iii_firmware","vendor":"epson"},{"product":"tm-t88vi-ihub_firmware","vendor":"epson"},{"product":"tm-t88vi_firmware","vendor":"epson"},{"product":"tm-t88vii_firmware","vendor":"epson"},{"product":"ub-e04_firmware","vendor":"epson"},{"product":"ub-r04_firmware","vendor":"epson"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"ESC/POS, a printer control language designed by Seiko Epson Corporation, lacks mechanisms for user authentication and command authorization, does not provide controls to restrict sources or destinations of network communication, and transmits commands without encryption or integrity protection.","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":"Missing authorization in ESC/POS","id":"CVE-2026-23767","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Server-side request forgery in lucy-xss-filter","id":"CVE-2026-23768"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2026-23766"},"products":["ESC/POS"],"published":"2026-03-05","related":[],"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-06","vendors":["Seiko Epson Corporation"]},"summary":"ESC/POS protocol lacks authentication and encryption, allowing attackers to execute arbitrary commands or modify data on compatible printers.","url":"https://insights.sbomify.com/CVE-2026-23767/"}
