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-2026-12819 in the wild and no public exploit code.\n\nAffected product: deltaww DVP-12SE. 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-2026-12819/ (Markdown: https://insights.sbomify.com/CVE-2026-12819/index.md)","id":"CVE-2026-12819","markdown":"https://insights.sbomify.com/CVE-2026-12819/index.md","name":"CVE-2026-12819","record":{"aliases":["GHSA-xpw2-pg2w-j67h"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Delta PLC","requires_auth":"none","summary":"Unauthenticated attackers can access and modify security-sensitive PLC functions via the exposed Modbus TCP service on Delta DVP-12SE devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Deltaww","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:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Delta Electronics DVP12SE PLC exposes a Modbus TCP service over a specified port without authentication or access control, permitting unauthenticated interaction with security-sensitive PLC functions.","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":"DVP-12SE Missing Authentication and Unauthorized Write access Vulnerability","id":"CVE-2026-12819","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":"FlowiseAI Flowise S3 Document Loader S3.ts path traversal","id":"CVE-2026-12821"},"packages":[],"prev":{"headline":"DVP-12SE Exposure of Sensitive Information Vulnerability","id":"CVE-2026-12818"},"products":["DVP-12SE"],"published":"2026-06-30","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":"2026-06-30","vendors":["deltaww"]},"summary":"Unauthenticated attackers can access and modify security-sensitive PLC functions via the exposed Modbus TCP service on Delta DVP-12SE devices.","url":"https://insights.sbomify.com/CVE-2026-12819/"}
