It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-2318 and fix it if it is affected.\n\nWhat it is: CVE-2023-2318 is a high-severity cross-site scripting vulnerability in MarkText, published on 19 Aug 2023. It can only be exploited from the same machine or local network, 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-2023-2318 exists.\n\nAffected product: MarkText. 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-2023-2318/ (Markdown: https://insights.sbomify.com/CVE-2023-2318/index.md)","id":"CVE-2023-2318","markdown":"https://insights.sbomify.com/CVE-2023-2318/index.md","name":"CVE-2023-2318","record":{"aliases":["GHSA-jv63-mj7w-v6v9"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MarkText markdown editor","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into pasting malicious text into MarkText, requiring an upgrade to secure the application.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"STAR_Labs","cpe":[{"product":"marktext","vendor":"marktext"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"DOM-based XSS in src/muya/lib/contentState/pasteCtrl.js in MarkText 0.17.1 and before on Windows, Linux and macOS allows arbitrary JavaScript code to run in the context of MarkText main window.
