Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16039 exists.\n\nAffected product: Unknown MStore API. 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-2026-16039/ (Markdown: https://insights.sbomify.com/CVE-2026-16039/index.md)","id":"CVE-2026-16039","markdown":"https://insights.sbomify.com/CVE-2026-16039/index.md","name":"CVE-2026-16039","record":{"aliases":["GHSA-wgmj-93jg-87w3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can access all WooCommerce orders and customer PII due to missing authorization checks on the vendor-orders endpoint.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The MStore API  WordPress plugin before 4.21.0 does not restrict its vendor-orders endpoint to the caller's own orders, allowing any authenticated user, including Subscribers, to read every WooCommerce order in the store together with each customer's personal information.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"MStore API \u003c 4.21.0 - Subscriber+ Order and Customer PII Disclosure via IDOR","id":"CVE-2026-16039","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":"MStore API \u003c 4.21.0 - Unauthenticated Product Review Creation","id":"CVE-2026-16041"},"packages":[],"prev":{"headline":"MStore API \u003c 4.21.0 - Unauthenticated Payment Bypass via Multiple Payment Gateways","id":"CVE-2026-16038"},"products":["MStore API"],"published":"2026-08-07","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-07","vendors":["Unknown"]},"summary":"Authenticated users can access all WooCommerce orders and customer PII due to missing authorization checks on the vendor-orders endpoint.","url":"https://insights.sbomify.com/CVE-2026-16039/"}
