An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-41923 and fix it if it is affected.\n\nWhat it is: CVE-2026-41923 is a critical command injection vulnerability in Shenzhen Yipu Commercial and Trading Co., Ltd WDR201A WiFi Extender, published on 4 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41923 exists.\n\nAffected product: Shenzhen Yipu Commercial and Trading Co., Ltd WDR201A WiFi Extender. 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-2026-41923/ (Markdown: https://insights.sbomify.com/CVE-2026-41923/index.md)","id":"CVE-2026-41923","markdown":"https://insights.sbomify.com/CVE-2026-41923/index.md","name":"CVE-2026-41923","record":{"aliases":["GHSA-2frf-w2p8-6vq5"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WiFi extender","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary shell commands on the WDR201A WiFi Extender via the internet.cgi gateway parameter.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the internet.cgi binary that allows unauthenticated remote attackers to execute arbitrary shell commands by injecting malicious input into the gateway POST parameter.
