An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-47875 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dompurify (npm): affected all versions; fixed in 2.5.0\n- dompurify (npm): affected all versions; fixed in 2.5.0\n- dompurify (npm): affected from 3.0.0; fixed in 3.1.3\n- dompurify (npm): affected from 3.0.0; fixed in 3.1.3\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-2024-47875/ (Markdown: https://insights.sbomify.com/CVE-2024-47875/index.md)","id":"CVE-2024-47875","markdown":"https://insights.sbomify.com/CVE-2024-47875/index.md","name":"CVE-2024-47875","record":{"aliases":["CLSA-2026-1792760535","DEBIAN-CVE-2024-47875","DSA-5790-1","GHSA-gx9m-whjm-85jf","MINI-cgwm-8wg3-6php","UBUNTU-CVE-2024-47875"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript XSS sanitizer","requires_auth":"none","summary":"An attacker can execute arbitrary JavaScript via nesting-based mXSS in DOMPurify, requiring an upgrade to patched versions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"dompurify","vendor":"cure53"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG.
