Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4947 in the wild and no public exploit code.\n\nAffected product: Yan\u0026Co WooCommerce EAN Payment Gateway. 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-2023-4947/ (Markdown: https://insights.sbomify.com/CVE-2023-4947/index.md)","id":"CVE-2023-4947","markdown":"https://insights.sbomify.com/CVE-2023-4947/index.md","name":"CVE-2023-4947","record":{"aliases":["GHSA-jhg8-jx4g-7x8h"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated contributors can modify order EAN data due to missing capability checks in the WooCommerce EAN Payment Gateway plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"woocommerce_ean_payment_gateway","vendor":"yanco"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The WooCommerce EAN Payment Gateway plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the refresh_order_ean_data AJAX action in versions up to 6.1.0.
