An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-20027 exists.\n\nAffected product: ZKTeco ZKBioSecurity. 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-2016-20027/ (Markdown: https://insights.sbomify.com/CVE-2016-20027/index.md)","id":"CVE-2016-20027","markdown":"https://insights.sbomify.com/CVE-2016-20027/index.md","name":"CVE-2016-20027","record":{"aliases":["GHSA-7v59-xppj-w9h9"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"ZKTeco ZKBioSecurity","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in user browsers via reflected XSS in ZKTeco ZKBioSecurity, potentially leading to session hijacking or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"ZKTeco ZKBioSecurity 3.0 contains multiple reflected cross-site scripting vulnerabilities that allow attackers to execute arbitrary HTML and script code by injecting malicious payloads through unsanitized parameters in multiple scripts.
