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-2026-4734 in the wild and no public exploit code.\n\nAffected product: yoyofr modizer. 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-2026-4734/ (Markdown: https://insights.sbomify.com/CVE-2026-4734/index.md)","id":"CVE-2026-4734","markdown":"https://insights.sbomify.com/CVE-2026-4734/index.md","name":"CVE-2026-4734","record":{"aliases":["GHSA-36m3-3x88-3x7w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Music production software","requires_auth":"none","summary":"A heap buffer overflow in Modizer allows attackers to execute arbitrary code or cause a denial of service via crafted input.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GovTech CSG","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:A/S:N/AU:Y/R:U/V:D/RE:L/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in yoyofr modizer (libs/libopenmpt/openmpt-trunk/include/premake/contrib/curl/lib modules).
