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-2026-18786/ (Markdown: https://insights.sbomify.com/CVE-2026-18786/index.md)","id":"CVE-2026-18786","markdown":"https://insights.sbomify.com/CVE-2026-18786/index.md","name":"CVE-2026-18786","record":{"aliases":["GHSA-8r6g-r9rq-8jr8"],"analysis":null,"analysis_generated_by":null,"assigner":"WPScan","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The CheckView  WordPress plugin before 2.3.2 does not restrict its REST API authentication filter to its own routes and unconditionally discards the authentication error raised for any request whose URI merely contains a CheckView  WordPress plugin before 2.3.2-specific string, making it possible for unauthenticated attackers to bypass the REST nonce check and perform any REST action available to a logged-in administrator, such as creating a new administrator account, via a crafted link an administrator is tricked into opening.","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":"CheckView \u003c 2.3.2 - Administrator Account Creation via REST API Authentication Bypass","id":"CVE-2026-18786","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"GL.iNet AX1800 RPC Endpoint oui-rpc.lua remove_rule command injection","id":"CVE-2026-18787"},"packages":[],"prev":{"headline":"o6 open62541 client_types_custom.c UA_Client_getRemoteDataTypes use after free","id":"CVE-2026-18785"},"products":["CheckView"],"published":"2026-08-10","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":"total"},"state":"PUBLISHED","updated":"2026-08-11","vendors":["Unknown"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-18786/"}
