An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16605 exists.\n\nAffected product: Unknown MultiVendorX. 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-2026-16605/ (Markdown: https://insights.sbomify.com/CVE-2026-16605/index.md)","id":"CVE-2026-16605","markdown":"https://insights.sbomify.com/CVE-2026-16605/index.md","name":"CVE-2026-16605","record":{"aliases":["GHSA-w6w9-w293-w3m5"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Authenticated vendors can view, modify, or delete other vendors' stores due to missing authorization checks in the REST API.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The MultiVendorX  WordPress plugin before 5.0.11 does not verify that the store targeted through its REST API belongs to the requesting vendor, allowing an authenticated vendor (Store Owner and above) to view, take over, permanently delete, or modify any other vendor's store on the marketplace.","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":"MultiVendorX \u003c 5.0.11 - Store Owner+ Cross-Vendor Store Takeover and Deletion via Missing Authorization","id":"CVE-2026-16605","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":"Unauthenticated remote code execution (pre-auth RCE) vulnerability in openFT for Linux and Oracle Solaris","id":"CVE-2026-16606"},"packages":[],"prev":{"headline":"Information disclosure in Passster","id":"CVE-2026-16604"},"products":["MultiVendorX"],"published":"2026-08-05","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":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Unknown"]},"summary":"Authenticated vendors can view, modify, or delete other vendors' stores due to missing authorization checks in the REST API.","url":"https://insights.sbomify.com/CVE-2026-16605/"}
