It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-22535 and fix it if it is affected.\n\nWhat it is: CVE-2026-22535 is a high-severity missing authorization vulnerability in EFACEC QC 60/90/120, published on 7 Jan 2026. 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-2026-22535 in the wild and no public exploit code.\n\nAffected product: EFACEC QC 60/90/120. 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-2026-22535/ (Markdown: https://insights.sbomify.com/CVE-2026-22535/index.md)","id":"CVE-2026-22535","markdown":"https://insights.sbomify.com/CVE-2026-22535/index.md","name":"CVE-2026-22535","record":{"aliases":["GHSA-jj3f-4mq7-82wx"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"EFACEC QC series","requires_auth":"low_privilege","summary":"An attacker with network access and credentials can modify critical parameters on EFACEC QC series devices due to unsecured MQTT communications.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"S21sec","cpe":[],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-1366","name":null}],"description":"An attacker with the ability to interact through the network and with access credentials, could, thanks to the unsecured (unencrypted) MQTT communications protocol, write on the server topics of the board that controls the MQTT communications","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":"FRAIL SECURITY IN MQTT PROTOCOL ALLOWS AN ATTACKER MODIFY CRITICAL PARAMETERS","id":"CVE-2026-22535","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"PRIVILEGE ESCALATION VIA SUDO COMMAND","id":"CVE-2026-22536"},"packages":[],"prev":{"headline":"WordPress Legacy Admin plugin \u003c= 9.5 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-22524"},"products":["QC 60/90/120"],"published":"2026-01-07","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":"2026-01-07","vendors":["EFACEC"]},"summary":"An attacker with network access and credentials can modify critical parameters on EFACEC QC series devices due to unsecured MQTT communications.","url":"https://insights.sbomify.com/CVE-2026-22535/"}
