Any signed-in user can exploit it over the 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-2023-4821 exists.\n\nAffected product: Unknown Drag and Drop Multiple File Upload for WooCommerce. 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-2023-4821/ (Markdown: https://insights.sbomify.com/CVE-2023-4821/index.md)","id":"CVE-2023-4821","markdown":"https://insights.sbomify.com/CVE-2023-4821/index.md","name":"CVE-2023-4821","record":{"aliases":["GHSA-9c5w-974x-xjxh"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Unauthenticated attackers can upload malicious SVG or SHTML files to execute scripts in victim browsers via stored XSS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"drag_and_drop_multiple_file_uploader","vendor":"codedropz"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Drag and Drop Multiple File Upload for WooCommerce WordPress plugin before 1.1.1 does not filter all potentially dangerous file extensions.
