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-2026-35226 in the wild and no public exploit code.\n\nAffected product: CODESYS PROFINET. 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-2026-35226/ (Markdown: https://insights.sbomify.com/CVE-2026-35226/index.md)","id":"CVE-2026-35226","markdown":"https://insights.sbomify.com/CVE-2026-35226/index.md","name":"CVE-2026-35226","record":{"aliases":["GHSA-jxhr-7f6w-54g7"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CODESYS PROFINET Controller","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial of service by sending malformed PROFINET data to trigger an out-of-bounds write and stop the PLC application.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An out‑of‑bounds write vulnerability in the CODESYS PROFINET Controller allows an unauthenticated attacker on the same network segment to send malformed PROFINET communication data that triggers an exception in the affected PLC application.
