38
FAUCET Score

CVE-2019-3810 describes a persistent Cross-Site Scripting (XSS) vulnerability in Moodle versions 3.6 to 3.6.1, 3.5 to 3.5.3, 3.4 to 3.4.6, and 3.1 to 3.1.15. The flaw allowed unescaped user full names, displayed on hover over profile images on the /userpix/ page, to execute malicious scripts. Rated Medium severity (CVSS 6.1), it requires user interaction (UI:R) and could lead to low impact on confidentiality and integrity (C:L/I:L). While not actively exploited in the wild (KEV: No) and lacking significant community discussion, a public exploit (EDB-49814) exists, indicating its potential for exploitation.
