{"affected":[{"product":"lms","source":"CNA: GitHub_M","vendor":"frappe","versions":[{"status":"affected","version":"< 2.54.0"}]}],"cveId":"CVE-2026-61805","cwes":["CWE-862"],"description":"Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.54.0, quiz submission records are not adequately authorized on the server. Through a `REST` bypass, an authenticated student can record a passing or perfect quiz result without their answers being verified, unlocking course completion and certificates. The student can also create a submission attributed to another user, exhausting that user's allowed attempts and blocking legitimate submissions. These integrity and availability issues are scoped to quiz results; they do not expose other users' data or grant elevated roles. This issue is fixed in version 2.54.0.","epss":{"date":"2026-11-04","percentile":0.12342,"score":0.00218},"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.3,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793834276450,"publishedAt":1793379702988,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/frappe/lms/security/advisories/GHSA-4566-2phx-68gh"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/frappe/lms/commit/876504f3900512f528b6e4a7bd3a15673eedd386"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/frappe/lms/tree/v2.54.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/frappe/lms/commit/876504f3900512f528b6e4a7bd3a15673eedd386"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/frappe/lms/security/advisories/GHSA-4566-2phx-68gh"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/frappe/lms/tree/v2.54.0"}],"remediation":[],"revision":"6c327749db6ee09d5877603acaac346460fb35189e46a3dfda07b2808eb7cd7f","sources":[{"modifiedAt":1793833360996,"name":"CNA: GitHub_M","retrievedAt":1793837325466,"url":"https://www.cve.org/CVERecord?id=CVE-2026-61805"},{"modifiedAt":1793834276450,"name":"NVD","retrievedAt":1793838191527,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61805"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793837328933,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61805"}],"ssvc":{"assessedAt":1793833348922,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Frappe LMS: Quiz result manipulation and cross-user submission forgery","updatedAt":1793838191527}
