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-2021-24943 exists.\n\nAffected product: Unknown Registrations for the Events Calendar – Event Registration Plugin. 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-2021-24943/ (Markdown: https://insights.sbomify.com/CVE-2021-24943/index.md)","id":"CVE-2021-24943","markdown":"https://insights.sbomify.com/CVE-2021-24943/index.md","name":"CVE-2021-24943","record":{"aliases":["GHSA-756m-jgjv-8g68"],"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":"none","summary":"Unauthenticated attackers can inject SQL via the event_id parameter in the rtec_send_unregister_link AJAX action, allowing unauthorized database access.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"registrations_for_the_events_calendar","vendor":"roundupwp"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"The Registrations for the Events Calendar WordPress plugin before 2.7.6 does not sanitise and escape the event_id in the rtec_send_unregister_link AJAX action (available to both unauthenticated and authenticated users) before using it in a SQL statement, leading to an unauthenticated SQL injection.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24943.yaml","stars":null,"title":"Registrations for the Events Calendar \u003c 2.7.6 - SQL Injection"}],"tier":"weaponised"},"has_fix":null,"headline":"Registrations for the Events Calendar \u003c 2.7.6 - Unauthenticated SQL Injection","id":"CVE-2021-24943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"sql_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Custom Dashboard \u0026 Login Page \u003c 7.0 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24944"},"packages":[],"prev":{"headline":"Menu Item Visibility Control \u003c= 0.5 - Admin+ Arbitrary PHP Code Execution","id":"CVE-2021-24942"},"products":["Registrations for the Events Calendar – Event Registration Plugin"],"published":"2021-12-06","related":[{"cvss_score":9.6,"headline":"Registrations for The Events Calendar \u003c 2.12.4 - Unauthenticated Stored XSS","id":"CVE-2024-7982","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":8.5,"headline":"WordPress Registrations for the Events Calendar plugin \u003c= 2.12.2 - SQL Injection vulnerability","id":"CVE-2024-39638","kev_date_added":null,"published":"2024-08-29"},{"cvss_score":6.1,"headline":"Registrations for The Events Calendar \u003c 2.13.4 - Admin+ Stored XSS","id":"CVE-2024-10703","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":6.1,"headline":"Registrations for the Events Calendar \u003c 2.7.10 - Reflected Cross-Site Scripting","id":"CVE-2021-25083","kev_date_added":null,"published":"2022-01-24"},{"cvss_score":6.1,"headline":"Registrations for The Events Calendar \u003c 2.7.5 - Reflected Cross-Site Scripting","id":"CVE-2021-24876","kev_date_added":null,"published":"2021-11-29"}],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject SQL via the event_id parameter in the rtec_send_unregister_link AJAX action, allowing unauthorized database access.","url":"https://insights.sbomify.com/CVE-2021-24943/"}
