An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2019-16935 and fix it if it is affected.\n\nWhat it is: CVE-2019-16935 is a medium-severity cross-site scripting vulnerability in Canonical Ubuntu Linux, published on 28 Sep 2019. 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-2019-16935 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2019-16935/ (Markdown: https://insights.sbomify.com/CVE-2019-16935/index.md)","id":"CVE-2019-16935","markdown":"https://insights.sbomify.com/CVE-2019-16935/index.md","name":"CVE-2019-16935","record":{"aliases":["ALPINE-CVE-2019-16935","CLEANSTART-2026-QJ43408","DEBIAN-CVE-2019-16935","GHSA-qhmv-wcg2-h8hx","PSF-2019-6","RHSA-2020:3911","UBUNTU-CVE-2019-16935"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Python standard library","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in clients visiting the XML-RPC server if the server title is set with untrusted input.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"python","vendor":"python"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field.
