An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82847 in the wild and no public exploit code.\n\nAffected product: Unknown Masteriyo LMS. 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-2026-82847/ (Markdown: https://insights.sbomify.com/CVE-2026-82847/index.md)","id":"CVE-2026-82847","markdown":"https://insights.sbomify.com/CVE-2026-82847/index.md","name":"CVE-2026-82847","record":{"aliases":["GHSA-8hqp-p78r-mqpg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress LMS plugin","requires_auth":"high_privilege","summary":"Instructors can inject malicious scripts into course fields, leading to stored XSS attacks against administrators in the Masteriyo LMS plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Masteriyo LMS  WordPress plugin before 3.4.1 does not sanitise and escape one of its course fields before outputting it back in the course editor, allowing users with the instructor role to perform Stored Cross-Site Scripting attacks against higher privileged users such as administrators.","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":"Masteriyo LMS \u003c 3.4.1 - Instructor+ Stored XSS via Course Highlights","id":"CVE-2026-82847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Masteriyo LMS 1.3.1 - 2.3.3 - Unauthenticated Course Enrollment Disclosure","id":"CVE-2026-82848"},"packages":[],"prev":{"headline":"Masteriyo LMS 1.18.0 - 2.3.3 - Instructor+ Stored XSS via Course Custom Fields","id":"CVE-2026-82846"},"products":["Masteriyo LMS"],"published":"2026-09-12","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":"total"},"state":"PUBLISHED","updated":"2026-09-12","vendors":["Unknown"]},"summary":"Instructors can inject malicious scripts into course fields, leading to stored XSS attacks against administrators in the Masteriyo LMS plugin.","url":"https://insights.sbomify.com/CVE-2026-82847/"}
