An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-26386 in the wild and no public exploit code.\n\nAffected product: Johnson Controls iSTAR Configuration Utility (ICU). 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-2025-26386/ (Markdown: https://insights.sbomify.com/CVE-2025-26386/index.md)","id":"CVE-2025-26386","markdown":"https://insights.sbomify.com/CVE-2025-26386/index.md","name":"CVE-2025-26386","record":{"aliases":["GHSA-chvq-5q36-924f"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"iSTAR Configuration Utility","requires_auth":"none","summary":"A stack-based buffer overflow in the iSTAR Configuration Utility can cause the host operating system to fail, requiring an upgrade to mitigate.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Johnson Controls iSTAR Configuration Utility (ICU) has Stack-based Buffer Overflow vulnerability.
