Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-87831 in the wild and no public exploit code.\n\nAffected product: Unknown Checkout Field Manager (Checkout Manager) 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-2026-87831/ (Markdown: https://insights.sbomify.com/CVE-2026-87831/index.md)","id":"CVE-2026-87831","markdown":"https://insights.sbomify.com/CVE-2026-87831/index.md","name":"CVE-2026-87831","record":{"aliases":["GHSA-qrgr-7qgf-2qv8"],"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 users can delete arbitrary media attachments belonging to other users due to missing ownership validation in the Checkout Field Manager plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"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 Checkout Field Manager (Checkout Manager) for WooCommerce WordPress plugin before 7.9.7 does not properly validate the ownership of an attachment before deleting it, allowing any authenticated user such as a customer to delete arbitrary media attachments belonging to other users.","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":"Checkout Field Manager \u003c 7.9.7 - Subscriber+ Arbitrary Attachment Deletion via Customer Address Custom Field","id":"CVE-2026-87831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Front End Users \u003c= 3.2.35 - Unauthenticated Membership Level and Account Status Self-Assignment","id":"CVE-2026-87835"},"packages":[],"prev":{"headline":"Apache WSS4J: Streaming WS-SecurityPolicy validation may skip element-protection checks.","id":"CVE-2026-87830"},"products":["Checkout Field Manager (Checkout Manager) for WooCommerce"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["Unknown"]},"summary":"Authenticated users can delete arbitrary media attachments belonging to other users due to missing ownership validation in the Checkout Field Manager plugin.","url":"https://insights.sbomify.com/CVE-2026-87831/"}
