It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-44469 and fix it if it is affected.\n\nWhat it is: CVE-2026-44469 is a high-severity vulnerability in CODESYS Development System, published on 26 May 2026. 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-2026-44469 in the wild and no public exploit code.\n\nAffected product: CODESYS Development System. 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-2026-44469/ (Markdown: https://insights.sbomify.com/CVE-2026-44469/index.md)","id":"CVE-2026-44469","markdown":"https://insights.sbomify.com/CVE-2026-44469/index.md","name":"CVE-2026-44469","record":{"aliases":["GHSA-fhx5-27vm-6mqj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CODESYS Development System","requires_auth":"low_privilege","summary":"A local attacker can exploit a race condition during installation to replace files, leading to privilege escalation in CODESYS Development System.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"development_system","vendor":"codesys"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"The affected product extracts installation files to a temporary directory with incorrect default permissions during administrative installation.
