Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-4212 and fix it if it is affected.\n\nWhat it is: CVE-2026-4212 is a high-severity memory corruption vulnerability in Dlink Dns-320 Firmware, published on 16 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-4212 exists.\n\nAffected product: Dlink Dns-320 Firmware. 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-2026-4212/ (Markdown: https://insights.sbomify.com/CVE-2026-4212/index.md)","id":"CVE-2026-4212","markdown":"https://insights.sbomify.com/CVE-2026-4212/index.md","name":"CVE-2026-4212","record":{"aliases":["GHSA-m5mx-7f32-mh68"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link NAS","requires_auth":"low_privilege","summary":"Remote attackers can trigger a stack-based buffer overflow in D-Link NAS devices via the download_mgr.cgi script, potentially leading to arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"dnr-202l_firmware","vendor":"dlink"},{"product":"dnr-326_firmware","vendor":"dlink"},{"product":"dns-1100-4_firmware","vendor":"dlink"},{"product":"dns-1200-05_firmware","vendor":"dlink"},{"product":"dns-120_firmware","vendor":"dlink"},{"product":"dns-1550-04_firmware","vendor":"dlink"},{"product":"dns-315l_firmware","vendor":"dlink"},{"product":"dns-320_firmware","vendor":"dlink"},{"product":"dns-320l_firmware","vendor":"dlink"},{"product":"dns-320lw_firmware","vendor":"dlink"},{"product":"dns-321_firmware","vendor":"dlink"},{"product":"dns-322l_firmware","vendor":"dlink"},{"product":"dns-323_firmware","vendor":"dlink"},{"product":"dns-325_firmware","vendor":"dlink"},{"product":"dns-326_firmware","vendor":"dlink"},{"product":"dns-327l_firmware","vendor":"dlink"},{"product":"dns-340l_firmware","vendor":"dlink"},{"product":"dns-343_firmware","vendor":"dlink"},{"product":"dns-345_firmware","vendor":"dlink"},{"product":"dns-726-4_firmware","vendor":"dlink"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"},{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A security vulnerability has been detected in D-Link DNS-120, DNR-202L, DNS-315L, DNS-320, DNS-320L, DNS-320LW, DNS-321, DNR-322L, DNS-323, DNS-325, DNS-326, DNS-327L, DNR-326, DNS-340L, DNS-343, DNS-345, DNS-726-4, DNS-1100-4, DNS-1200-05 and DNS-1550-04 up to 20260205.
