An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-6987 and fix it if it is affected.\n\nWhat it is: CVE-2020-6987 is a high-severity vulnerability in Moxa PT-7528 series firmware, Version 4.0 or lower, PT-7828 series firmware, Version 3.9 or lower, published on 24 Mar 2020. 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-2020-6987 in the wild and no public exploit code.\n\nAffected product: Moxa PT-7528 series firmware, Version 4.0 or lower, PT-7828 series firmware, Version 3.9 or lower. 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-2020-6987/ (Markdown:
