OpenBlocks IDM RX1 (FW5.0.x), published on 6 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-2026-21411 in the wild and no public exploit code.\n\nAffected product: Plat'Home Co.,Ltd. OpenBlocks IDM RX1 (FW5.0.x). 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-2026-21411/ (Markdown: https://insights.sbomify.com/CVE-2026-21411/index.md)","id":"CVE-2026-21411","markdown":"https://insights.sbomify.com/CVE-2026-21411/index.md","name":"CVE-2026-21411","record":{"aliases":["GHSA-xm4x-3r5h-vwfr"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenBlocks IoT device","requires_auth":"none","summary":"Attackers can bypass administrator authentication to change passwords on OpenBlocks IoT devices, requiring firmware upgrades to mitigate.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"Authentication bypass issue exists in OpenBlocks series versions prior to FW5.0.8, which may allow an attacker to bypass administrator authentication and change the password.","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":"Auth bypass in OpenBlocks IDM RX1 (FW5.0.x)","id":"CVE-2026-21411","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in LibRaw","id":"CVE-2026-21413"},"packages":[],"prev":{"headline":"InSAT MasterSCADA BUK-TS SQL Injection","id":"CVE-2026-21410"},"products":["OpenBlocks IDM RX1 (FW5.0.x)","OpenBlocks IX9 models with FW (FW5.0.x)","OpenBlocks IoT DX1 (FW5.0.x)","OpenBlocks IoT EX/BX models (FW5.0.x)","OpenBlocks IoT FX1 (FW5.0.x)","OpenBlocks IoT VX2 (FW5.0.x)"],"published":"2026-01-06","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":"2026-01-06","vendors":["Plat'Home Co.,Ltd."]},"summary":"Attackers can bypass administrator authentication to change passwords on OpenBlocks IoT devices, requiring firmware upgrades to mitigate.","url":"https://insights.sbomify.com/CVE-2026-21411/"}
