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-2026-19477 and fix it if it is affected.\n\nWhat it is: CVE-2026-19477 is a high-severity memory corruption vulnerability in MCC Universal Library for Linux (uldaq), published on 17 Sep 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-2026-19477 in the wild and no public exploit code.\n\nAffected product: MCC Universal Library for Linux (uldaq). 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-2026-19477/ (Markdown: https://insights.sbomify.com/CVE-2026-19477/index.md)","id":"CVE-2026-19477","markdown":"https://insights.sbomify.com/CVE-2026-19477/index.md","name":"CVE-2026-19477","record":{"aliases":["GHSA-9jr3-33mw-g6jc","GHSA-j395-f5mc-4872"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux data acquisition library","requires_auth":"none","summary":"A stack-based buffer overflow in the MCC Universal Library for Linux allows attackers to execute arbitrary code or disclose sensitive information.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NI","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"There\nis stack-based buffer overflow vulnerability recently discovered in MCC Universal Library for Linux (uldaq).  This may result in information disclosure or arbitrary code\nexecution.
