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-2026-16736 exists.\n\nAffected product: Unknown User Registration \u0026 Membership. 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-2026-16736/ (Markdown: https://insights.sbomify.com/CVE-2026-16736/index.md)","id":"CVE-2026-16736","markdown":"https://insights.sbomify.com/CVE-2026-16736/index.md","name":"CVE-2026-16736","record":{"aliases":["GHSA-r7cf-cqmf-q6pj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can create accounts in the User Registration \u0026 Membership plugin even when registration is disabled by administrators.","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:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"The User Registration \u0026 Membership  WordPress plugin before 5.2.6 does not enforce the site's registration-disabled setting when processing registration-form submissions, allowing unauthenticated users to create new accounts even when the administrator has turned off open registration.","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":"User Registration \u0026 Membership \u003c 5.2.6 - Unauthenticated Account Creation While Registration Disabled","id":"CVE-2026-16736","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":"WP Travel Engine \u003c 6.8.5 - Unauthenticated Booking Details Disclosure and Modification via wte_add_trip_to_cart","id":"CVE-2026-16737"},"packages":[],"prev":{"headline":"release-it conventional-changelog Changelog File index.js writeChangelog os command injection","id":"CVE-2026-16735"},"products":["User Registration \u0026 Membership"],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Unknown"]},"summary":"Unauthenticated attackers can create accounts in the User Registration \u0026 Membership plugin even when registration is disabled by administrators.","url":"https://insights.sbomify.com/CVE-2026-16736/"}
