16
FAUCET Score

CVE-2015-5269 is a cross-site scripting (XSS) vulnerability affecting Moodle versions through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2. This medium-severity vulnerability (CVSS 5.4) allows remote authenticated users to inject arbitrary web script or HTML by manipulating a grouping description, requiring user interaction. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability could lead to client-side attacks like session hijacking or defacement. Community discussion is minimal, and it is not listed on the CISA KEV catalog or Hot List.
