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-2021-24562 in the wild and no public exploit code.\n\nAffected product: Unknown LMS by LifterLMS – Online Course, Membership \u0026 Learning Management System Plugin for WordPress. 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-2021-24562/ (Markdown: https://insights.sbomify.com/CVE-2021-24562/index.md)","id":"CVE-2021-24562","markdown":"https://insights.sbomify.com/CVE-2021-24562/index.md","name":"CVE-2021-24562","record":{"aliases":["GHSA-h388-6737-2grv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress LMS plugin","requires_auth":"none","summary":"Students can view other students' answers and grades due to an Insecure Direct Object Reference vulnerability in the LifterLMS plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"lifterlms","vendor":"lifterlms"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The LMS by LifterLMS – Online Course, Membership \u0026 Learning Management System Plugin for WordPress plugin before 4.21.2 was affected by an IDOR issue, allowing students to see other student answers and grades","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"LifterLMS \u003c 4.21.2 - Access Other Student Grades/Answers via IDOR","id":"CVE-2021-24562","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Frontend Uploader \u003c= 1.3.2 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2021-24563"},"packages":[],"prev":{"headline":"WP SMS \u003c 5.4.13 - Authenticated Stored Cross-Site Scripting","id":"CVE-2021-24561"},"products":["LMS by LifterLMS – Online Course, Membership \u0026 Learning Management System Plugin for WordPress"],"published":"2021-08-23","related":[{"cvss_score":9.8,"headline":"File upload in LifterLMS Wordpress Plugin","id":"CVE-2020-6008","kev_date_added":null,"published":"2020-03-31"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-15896","kev_date_added":null,"published":"2019-09-10"},{"cvss_score":9.3,"headline":"WordPress LifterLMS plugin \u003c= 8.0.6 - SQL Injection Vulnerability","id":"CVE-2025-52717","kev_date_added":null,"published":"2025-06-27"},{"cvss_score":8.8,"headline":"LifterLMS – WordPress LMS Plugin for eLearning \u003c= 7.6.2 - Authenticated (Contributor+) SQL Injection via Shortcode","id":"CVE-2024-4743","kev_date_added":null,"published":"2024-06-05"},{"cvss_score":7.2,"headline":"LifterLMS \u003c= 7.7.5 - Authenticated (Admin+) SQL Injection","id":"CVE-2024-7349","kev_date_added":null,"published":"2024-09-06"},{"cvss_score":6.1,"headline":"LifterLMS – WP LMS for eLearning, Online Courses, \u0026 Quizzes \u003c 8.0.1 - Reflected XSS","id":"CVE-2024-13619","kev_date_added":null,"published":"2025-05-15"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Students can view other students' answers and grades due to an Insecure Direct Object Reference vulnerability in the LifterLMS plugin.","url":"https://insights.sbomify.com/CVE-2021-24562/"}
