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-2026-24240 and fix it if it is affected.\n\nWhat it is: CVE-2026-24240 is a high-severity unsafe deserialization vulnerability in NVIDIA Megatron-Bridge, published on 1 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-2026-24240 in the wild and no public exploit code.\n\nAffected product: NVIDIA Megatron-Bridge. 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-2026-24240/ (Markdown: https://insights.sbomify.com/CVE-2026-24240/index.md)","id":"CVE-2026-24240","markdown":"https://insights.sbomify.com/CVE-2026-24240/index.md","name":"CVE-2026-24240","record":{"aliases":["GHSA-6j24-28g2-2556"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","privilege_escalation","data_modify","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NVIDIA Megatron Bridge","requires_auth":"none","summary":"An attacker can exploit untrusted data deserialization in NVIDIA Megatron Bridge to execute code, escalate privileges, tamper with data, or disclose information.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"nemo_megatron_bridge","vendor":"nvidia"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"NVIDIA Megatron Bridge for Linux contains a vulnerability where an attacker could cause deserialization of untrusted data.
