The attack can be triggered by legitimate administrators or users with upload permissions.", "description_and_impact": "Frappe Learning Management System allows user\u2011generated content. The vulnerability arises in versions 2.44.0 and earlier where an attacker can craft an image filename containing malicious JavaScript that is stored and later rendered within course or job pages. The stored XSS flaw can execute arbitrary script in the context of any user who views the page, potentially leading to credential theft, session hijacking or defacement.", "risk_and_exploitability": "The CVSS score is 1.3, indicating low severity, and the EPSS score is under 1%, suggesting a low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. The attack requires uploading a malicious filename, which is typically restricted to users with upload privileges; the flaw is client\u2011side only and does not provide remote code execution on the server. Exploitation would require a user to view the affected pages, making it a relatively low\u2011risk asset but still worth addressing to prevent phishing and other XSS attacks."}}}}, "created": "2026-01-15T08:03:17.822310+00:00", "updated": "2026-04-18T16:15:04.611350+00:00", "vendors": ["frappe", "frappe$PRODUCT$frappe", "frappe$PRODUCT$frappe_lms"]}
