Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-4196 and fix it if it is affected.\n\nWhat it is: CVE-2026-4196 is a medium-severity command injection vulnerability in Dlink Dns-320 Firmware, published on 15 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-2026-4196 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-2026-4196/ (Markdown: https://insights.sbomify.com/CVE-2026-4196/index.md)","id":"CVE-2026-4196","markdown":"https://insights.sbomify.com/CVE-2026-4196/index.md","name":"CVE-2026-4196","record":{"aliases":["GHSA-fvg7-m8g3-2hjj"],"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 execute arbitrary commands on D-Link NAS devices via the remote_backup.cgi script, potentially compromising the device.","user_interaction":"not_required","vuln_class":"command_injection"},"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":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A vulnerability has been found 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.
