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-2026-81855 in the wild and no public exploit code.\n\nAffected product: Wärtsilä FOS-Onboard. 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-2026-81855/ (Markdown: https://insights.sbomify.com/CVE-2026-81855/index.md)","id":"CVE-2026-81855","markdown":"https://insights.sbomify.com/CVE-2026-81855/index.md","name":"CVE-2026-81855","record":{"aliases":["GHSA-j2xg-7hvh-hxm5"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Marine automation system","requires_auth":"none","summary":"Attackers can exploit a hard-coded cryptographic key in the Wärtsilä FOS-Onboard robot testing framework to bypass authentication and potentially take over accounts.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A hardcoded cryptographic client authentication key vulnerability exists in the robot testing framework component of Wärtsilä FOS-Onboard.","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":"Wärtsilä FOS-Onboard Use of Hard-coded Cryptographic Key","id":"CVE-2026-81855","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Terminal escape sequence injection in Hex via unneutralized server-supplied output","id":"CVE-2026-81856"},"packages":[],"prev":{"headline":"AshAdmin composite primary key decoding accepts arbitrary fields, enabling a secret-attribute oracle","id":"CVE-2026-81853"},"products":["FOS-Onboard"],"published":"2026-09-15","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Wärtsilä"]},"summary":"Attackers can exploit a hard-coded cryptographic key in the Wärtsilä FOS-Onboard robot testing framework to bypass authentication and potentially take over accounts.","url":"https://insights.sbomify.com/CVE-2026-81855/"}
