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-2023-0835 exists.\n\nAffected packages and fixed versions:\n- markdown-pdf (npm): affected all versions up to 11.0.0; no fix listed\n- markdown-pdf (npm): affected all versions up to 11.0.0; no fix listed\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-2023-0835/ (Markdown: https://insights.sbomify.com/CVE-2023-0835/index.md)","id":"CVE-2023-0835","markdown":"https://insights.sbomify.com/CVE-2023-0835/index.md","name":"CVE-2023-0835","record":{"aliases":["GHSA-qghr-877h-f9jh"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js markdown library","requires_auth":"none","summary":"An attacker can exploit Server-Side XSS in markdown-pdf to read arbitrary local files from the server.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[{"product":"markdown-pdf","vendor":"markdown-pdf_project"}],"cvss":{"score":8.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"markdown-pdf version 11.0.0 allows an external attacker to remotely obtain arbitrary local files.
