It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-8313 and fix it if it is affected.\n\nWhat it is: CVE-2026-8313 is a high-severity memory corruption vulnerability in Rockwell Automation Arena® Simulation, published on 14 Jul 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-8313 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation Arena® Simulation. 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-2026-8313/ (Markdown: https://insights.sbomify.com/CVE-2026-8313/index.md)","id":"CVE-2026-8313","markdown":"https://insights.sbomify.com/CVE-2026-8313/index.md","name":"CVE-2026-8313","record":{"aliases":["GHSA-h5wm-63j8-q5vc"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arena Simulation software","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious file in Rockwell Arena Simulation due to an out-of-bounds write.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[{"product":"arena","vendor":"rockwellautomation"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A security issue exists within Arena® Simulation due to a memory corruption vulnerability in the linker.exe (Siman) component.
