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-2026-8508 and fix it if it is affected.\n\nWhat it is: CVE-2026-8508 is a medium-severity authentication bypass vulnerability in Zyxel WAX650S firmware, published on 4 Aug 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-2026-8508 in the wild and no public exploit code.\n\nAffected product: Zyxel WAX650S 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-2026-8508/ (Markdown: https://insights.sbomify.com/CVE-2026-8508/index.md)","id":"CVE-2026-8508","markdown":"https://insights.sbomify.com/CVE-2026-8508/index.md","name":"CVE-2026-8508","record":{"aliases":["GHSA-hq2r-whw2-gr82"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel wireless AP","requires_auth":"none","summary":"An attacker on the WLAN can bypass captive portal authentication in Zyxel WAX650S firmware due to improper authentication in social_login.cgi.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An improper authentication vulnerability in the \"social_login.cgi\" CGI program in Zyxel WAX650S firmware versions through 7.10(ABRM.4)C0 could allow an attacker on the WLAN to bypass captive portal authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-16","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-16T16:03:29Z","kind":"github_poc","ref":"https://github.com/minanagehsalalma/zyxel-social-login-bypass-cve-2026-8508","stars":0,"title":"Public writeup, PoC, and emulation materials for CVE-2026-8508 affecting Zyxel captive-portal social login."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in WAX650S firmware","id":"CVE-2026-8508","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Chrome","id":"CVE-2026-8509"},"packages":[],"prev":{"headline":"Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out-of-bounds (OOB) write flaws","id":"CVE-2026-8507"},"products":["WAX650S firmware"],"published":"2026-08-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-04","vendors":["Zyxel"]},"summary":"An attacker on the WLAN can bypass captive portal authentication in Zyxel WAX650S firmware due to improper authentication in social_login.cgi.","url":"https://insights.sbomify.com/CVE-2026-8508/"}
