An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2027 in the wild and no public exploit code.\n\nAffected product: zanematthew ZM Ajax Login \u0026 Register. 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-2023-2027/ (Markdown: https://insights.sbomify.com/CVE-2023-2027/index.md)","id":"CVE-2023-2027","markdown":"https://insights.sbomify.com/CVE-2023-2027/index.md","name":"CVE-2023-2027","record":{"aliases":["GHSA-x4hx-qqp4-qp78"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication and log in as any existing user, including administrators, via the Facebook login feature.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"zm_ajax_login_\\\u0026_register","vendor":"zm_ajax_login_\\\u0026_register_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"The ZM Ajax Login \u0026 Register plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.0.2.
