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-2023-51543 in the wild and no public exploit code.\n\nAffected product: Metagauss RegistrationMagic. 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-2023-51543/ (Markdown: https://insights.sbomify.com/CVE-2023-51543/index.md)","id":"CVE-2023-51543","markdown":"https://insights.sbomify.com/CVE-2023-51543/index.md","name":"CVE-2023-51543","record":{"aliases":["GHSA-8gc7-mjjc-5vm3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can bypass IP-based access restrictions in the RegistrationMagic plugin to access protected functionality.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"registrationmagic","vendor":"metagauss"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Authentication Bypass by Spoofing vulnerability in Metagauss RegistrationMagic allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects RegistrationMagic: from n/a through 5.2.5.0.","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":"WordPress RegistrationMagic plugin \u003c= 5.2.5.0 - IP Limit Bypass vulnerability","id":"CVE-2023-51543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress RegistrationMagic plugin \u003c= 5.2.5.0 - Form Submission Limit Bypass vulnerability","id":"CVE-2023-51544"},"packages":[],"prev":{"headline":"WordPress Branda plugin \u003c= 3.4.14 - IP Restriction Bypass vulnerability","id":"CVE-2023-51542"},"products":["RegistrationMagic"],"published":"2024-06-04","related":[{"cvss_score":9.8,"headline":"RegistrationMagic - Custom Registration Forms \u003c= 3.7.9.2 - PHP Object Injection","id":"CVE-2017-20208","kev_date_added":null,"published":"2025-10-18"},{"cvss_score":9.8,"headline":"Auth bypass in RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login","id":"CVE-2024-10508","kev_date_added":null,"published":"2024-11-09"},{"cvss_score":9.8,"headline":"RegistrationMagic \u003c= 5.2.1.0 - Authentication Bypass","id":"CVE-2023-2499","kev_date_added":null,"published":"2023-05-16"},{"cvss_score":9.8,"headline":"RegistrationMagic \u003c= 5.0.1.7 Authentication Bypass","id":"CVE-2021-4073","kev_date_added":null,"published":"2021-12-14"},{"cvss_score":8.8,"headline":"SQL injection in RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login","id":"CVE-2024-1990","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.8,"headline":"Privilege escalation in RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login","id":"CVE-2024-1991","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-9454","kev_date_added":null,"published":"2020-03-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Metagauss"]},"summary":"Attackers can bypass IP-based access restrictions in the RegistrationMagic plugin to access protected functionality.","url":"https://insights.sbomify.com/CVE-2023-51543/"}
