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-2026-28205 in the wild and no public exploit code.\n\nAffected product: OpenPLC_V3. 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-2026-28205/ (Markdown: https://insights.sbomify.com/CVE-2026-28205/index.md)","id":"CVE-2026-28205","markdown":"https://insights.sbomify.com/CVE-2026-28205/index.md","name":"CVE-2026-28205","record":{"aliases":["GHSA-3r9q-7hff-7fm4"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenPLC_V3","requires_auth":"none","summary":"An attacker can bypass authentication via an API to gain unauthorized access to the OpenPLC_V3 system due to insecure default initialization.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"openplc_v3_firmware","vendor":"openplcproject"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"OpenPLC_V3 is vulnerable to an Initialization of a Resource with an Insecure Default vulnerability which could allow an attacker to gain access to the system by bypassing authentication via an API.","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":"Initialization of a resource with an insecure default in OpenPLC_V3","id":"CVE-2026-28205","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Zen-C Vulnerable to Command Injection via Malicious Output Filename","id":"CVE-2026-28207"},"packages":[],"prev":{"headline":"CTEK Chargeportal Insufficiently Protected Credentials","id":"CVE-2026-28204"},"products":["OpenPLC_V3"],"published":"2026-04-09","related":[{"cvss_score":9.2,"headline":"Plaintext storage of a password in OpenPLC_V3","id":"CVE-2026-35556","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":9,"headline":"Memory corruption in OpenPLC v3","id":"CVE-2024-34026","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-31630","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":8.7,"headline":"Missing Authorization in OpenPLC_V3","id":"CVE-2026-35063","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":7.5,"headline":"Denial of service in OpenPLC v3","id":"CVE-2024-36980","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":7.5,"headline":"Denial of service in OpenPLC v3","id":"CVE-2024-36981","kev_date_added":null,"published":"2024-09-18"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-10","vendors":["OpenPLC_V3"]},"summary":"An attacker can bypass authentication via an API to gain unauthorized access to the OpenPLC_V3 system due to insecure default initialization.","url":"https://insights.sbomify.com/CVE-2026-28205/"}
