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-2023-28421 in the wild and no public exploit code.\n\nAffected product: Winwar Media WordPress Email Marketing Plugin – WP Email Capture. 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-2023-28421/ (Markdown: https://insights.sbomify.com/CVE-2023-28421/index.md)","id":"CVE-2023-28421","markdown":"https://insights.sbomify.com/CVE-2023-28421/index.md","name":"CVE-2023-28421","record":{"aliases":["GHSA-hf9h-c8cv-r62j"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"An attacker can access sensitive information from the WP Email Capture plugin without authorization, requiring a plugin update.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"wp_email_capture","vendor":"winwar"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Winwar Media WordPress Email Marketing Plugin – WP Email Capture.This issue affects WordPress Email Marketing Plugin – WP Email Capture: from n/a through 3.10.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"WordPress WordPress Email Marketing Plugin – WP Email Capture Plugin \u003c= 3.10 is vulnerable to Sensitive Data Exposure","id":"CVE-2023-28421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Event Manager for WooCommerce Plugin \u003c= 3.8.6 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-28422"},"packages":[],"prev":{"headline":"WordPress Custom Options Plus Plugin \u003c= 1.8.1 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-28420"},"products":["WordPress Email Marketing Plugin – WP Email Capture"],"published":"2023-12-21","related":[{"cvss_score":5.9,"headline":"Cross-site scripting in WP Email Capture","id":"CVE-2023-23723","kev_date_added":null,"published":"2023-05-02"},{"cvss_score":4.3,"headline":"Cross-site request forgery in WP Email Capture","id":"CVE-2023-23724","kev_date_added":null,"published":"2023-05-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Winwar Media"]},"summary":"An attacker can access sensitive information from the WP Email Capture plugin without authorization, requiring a plugin update.","url":"https://insights.sbomify.com/CVE-2023-28421/"}
