An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-85114 and fix it if it is affected.\n\nWhat it is: CVE-2026-85114 is a high-severity path traversal vulnerability in Siemens .NET Client Library for SIMATIC S7 Webserver API, published on 13 Oct 2026. 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-2026-85114 in the wild and no public exploit code.\n\nAffected product: Siemens .NET Client Library for SIMATIC S7 Webserver API. 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-2026-85114/ (Markdown: https://insights.sbomify.com/CVE-2026-85114/index.md)","id":"CVE-2026-85114","markdown":"https://insights.sbomify.com/CVE-2026-85114/index.md","name":"CVE-2026-85114","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens S7 Webserver API","requires_auth":"none","summary":"Attackers can write arbitrary files outside the intended directory via manipulated ticket responses, potentially overwriting existing files.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability has been identified in .NET Client Library for SIMATIC S7 Webserver API (All versions \u003c V3.3.61).
