An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-20601 and fix it if it is affected.\n\nWhat it is: CVE-2021-20601 is a high-severity vulnerability in GOT2000 series GT27 model; GOT2000 series GT25 model; GOT2000 series GT23 model; GOT2000 series GT21 model; GOT SIMPLE series GS21 model; GT SoftGOT2000, published on 23 Nov 2021. 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-2021-20601 in the wild and no public exploit code.\n\nAffected product: GOT2000 series GT27 model; GOT2000 series GT25 model; GOT2000 series GT23 model; GOT2000 series GT21 model; GOT SIMPLE series GS21 model; GT SoftGOT2000. 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-2021-20601/ (Markdown:
