20
FAUCET Score

CVE-2016-2190 is a medium-severity vulnerability affecting multiple versions of Moodle (through 2.6.11, 2.7.x before 2.7.13, 2.8.x before 2.8.11, 2.9.x before 2.9.5, and 3.0.x before 3.0.3). It allows remote attackers to obtain sensitive URL information by reading Referer logs due to improper link restriction. The attack vector is network-based with low complexity, requiring no privileges or user interaction, and its potential impact is limited to information disclosure (CVSS 5.3). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
