An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19852 in the wild and no public exploit code.\n\nAffected product: CyberTutor NewSiteServer (NSS). 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-2026-19852/ (Markdown: https://insights.sbomify.com/CVE-2026-19852/index.md)","id":"CVE-2026-19852","markdown":"https://insights.sbomify.com/CVE-2026-19852/index.md","name":"CVE-2026-19852","record":{"aliases":["GHSA-q3pc-8mvq-c8v3"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NewSiteServer web application","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary files, including malicious HTML, to NewSiteServer, enabling cross-site scripting and potential code execution.","user_interaction":"required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"NewSiteServer (NSS) developed by CyberTutor has an Arbitrary File Upload vulnerability.
