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-2026-7256 and fix it if it is affected.\n\nWhat it is: CVE-2026-7256 is a high-severity command injection vulnerability in Zyxel WRE6505 v2 firmware, published on 12 May 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-2026-7256 in the wild and no public exploit code.\n\nAffected product: Zyxel WRE6505 v2 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-2026-7256/ (Markdown: https://insights.sbomify.com/CVE-2026-7256/index.md)","id":"CVE-2026-7256","markdown":"https://insights.sbomify.com/CVE-2026-7256/index.md","name":"CVE-2026-7256","record":{"aliases":["GHSA-c7j6-24cr-x2rf"],"analysis":{"component_type":"network_device","fix_type":"end_of_life","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel range extender","requires_auth":"none","summary":"Adjacent attackers can execute OS commands on unsupported Zyxel WRE6505 v2 devices via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"wre6505_firmware","vendor":"zyxel"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"** UNSUPPORTED WHEN ASSIGNED ** A command injection vulnerability in the CGI program of Zyxel WRE6505 v2 firmware version V1.00(ABDV.3)C0 could allow an adjacent attacker on the LAN to execute operating system (OS) commands on a vulnerable device by sending a crafted HTTP request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Command injection in WRE6505 v2 firmware","id":"CVE-2026-7256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in WRE6505 v2 firmware","id":"CVE-2026-7257"},"packages":[],"prev":{"headline":"Auth bypass in WRE6505 v2 firmware","id":"CVE-2026-7255"},"products":["WRE6505 v2 firmware"],"published":"2026-05-12","related":[{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2017-7964","kev_date_added":null,"published":"2017-04-19"},{"cvss_score":6.5,"headline":"Auth bypass in WRE6505 v2 firmware","id":"CVE-2026-7255","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":4.5,"headline":"Cross-site scripting in WRE6505 v2 firmware","id":"CVE-2026-6058","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":4.4,"headline":"Information disclosure in WRE6505 v2 firmware","id":"CVE-2026-7257","kev_date_added":null,"published":"2026-05-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-12","vendors":["Zyxel"]},"summary":"Adjacent attackers can execute OS commands on unsupported Zyxel WRE6505 v2 devices via crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2026-7256/"}
