An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16041 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-2026-16041/ (Markdown: https://insights.sbomify.com/CVE-2026-16041/index.md)","id":"CVE-2026-16041","markdown":"https://insights.sbomify.com/CVE-2026-16041/index.md","name":"CVE-2026-16041","record":{"aliases":["GHSA-9px3-jf5v-3473"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can create fake product reviews on WooCommerce stores configured to restrict reviews to verified owners.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The MStore API  WordPress plugin before 4.21.0 does not perform authorization or purchase-ownership checks on its REST product-review creation route, allowing an unauthenticated attacker to create WooCommerce product reviews with an attacker-chosen reviewer name, email and star rating on stores configured to accept reviews only from verified owners.","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 - Unauthenticated Product Review Creation","id":"CVE-2026-16041","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":"LWS Optimize \u003c 3.4 - Subscriber+ Cache Deletion","id":"CVE-2026-16042"},"packages":[],"prev":{"headline":"MStore API \u003c 4.21.0 - Subscriber+ Order and Customer PII Disclosure via IDOR","id":"CVE-2026-16039"},"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-07","vendors":["Unknown"]},"summary":"Unauthenticated attackers can create fake product reviews on WooCommerce stores configured to restrict reviews to verified owners.","url":"https://insights.sbomify.com/CVE-2026-16041/"}
