An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-81340 in the wild and no public exploit code.\n\nAffected product: Unknown MasterStudy LMS WordPress 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-2026-81340/ (Markdown: https://insights.sbomify.com/CVE-2026-81340/index.md)","id":"CVE-2026-81340","markdown":"https://insights.sbomify.com/CVE-2026-81340/index.md","name":"CVE-2026-81340","record":{"aliases":["GHSA-332v-j356-q3mj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress LMS plugin","requires_auth":"high_privilege","summary":"Instructors can manipulate any order via IDOR to grant free enrolments or revoke paid access, requiring an upgrade to fix.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":3.8,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The MasterStudy LMS WordPress Plugin  WordPress plugin before 3.7.50 does not perform per-object ownership or capability checks when updating orders through its REST API, allowing users with the Instructor role to modify any order on the site, granting free course enrolment, revoking other users' paid enrolments, and tampering with order notes.","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":"MasterStudy LMS \u003c 3.7.50 - Instructor+ Order Status Manipulation via IDOR","id":"CVE-2026-81340","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":"wolfEngine reuses the AES-CCM nonce on TLS 1.2 / DTLS 1.2 records","id":"CVE-2026-81341"},"packages":[],"prev":{"headline":"MasterStudy LMS \u003c 3.7.50 - Subscriber+ Quiz Attempt Grade Disclosure via IDOR","id":"CVE-2026-81339"},"products":["MasterStudy LMS WordPress Plugin"],"published":"2026-09-18","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Unknown"]},"summary":"Instructors can manipulate any order via IDOR to grant free enrolments or revoke paid access, requiring an upgrade to fix.","url":"https://insights.sbomify.com/CVE-2026-81340/"}
