{"schema":"threatline.record/2","record":{"id":"CVE-2026-112329","aliases":[],"summary":"Sensei LMS 4.26.4 Broken Access Control via save_new_message","details":"The Sensei LMS WordPress plugin before 4.26.4 contains a broken access control vulnerability in the legacy save_new_message handler hooked on the init action, which validates only a generic nonce without verifying course enrollment or restricting post_id to valid post types. Authenticated attackers, including unprivileged Subscribers, can supply an arbitrary post_id for any course, lesson, or quiz to create a private message addressed to that post's author, bypassing the enrollment checks enforced by the newer REST send-message controller.","categories":["Unclassified"],"product":"Sensei LMS","vendor":"Automattic","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112329","source_modified_at":"2026-10-22T02:58:48.591Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Sensei LMS","vendor":"Automattic","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"4.26.4"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112329","source_modified_at":"2026-10-22T02:58:48.591Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Sensei LMS","ecosystem":null},"version":"4.26.4","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0018,"percentile":0.07232,"score_date":"2026-10-23"},"published_at":"2026-10-19T14:45:24.844Z","modified_at":"2026-10-22T02:58:48.591Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112329","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-22T02:58:48.591Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112329","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://senseilms.com/release-notes/","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/sensei-lms-broken-access-control-via-save-new-message","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-22T02:58:38.469351Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-22T02:58:48.591Z","content_hash":"b6638920093b2a7c9213311458323adeb0338d959fcd59b0aa0b68c7b5a7f86d"}}
