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-2020-27176 and fix it if it is affected.\n\nWhat it is: CVE-2020-27176 is a high-severity cross-site scripting vulnerability in n/a, published on 16 Oct 2020. 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-2020-27176 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-27176/ (Markdown: https://insights.sbomify.com/CVE-2020-27176/index.md)","id":"CVE-2020-27176","markdown":"https://insights.sbomify.com/CVE-2020-27176/index.md","name":"CVE-2020-27176","record":{"aliases":["GHSA-q367-49gp-hvp2"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Markdown editor","requires_auth":"none","summary":"Mutation XSS in Mark Text allows remote code execution via source code mode HTML parsing.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"marktext","vendor":"marktext"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:H/AV:N/A:H/C:H/I:H/PR:N/S:C/UI:R","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Mutation XSS exists in Mark Text through 0.16.2 that leads to Remote Code Execution.
