21
FAUCET Score

CVE-2017-14313 describes a Cross-Site Scripting (XSS) vulnerability in the Shibboleth plugin for WordPress, specifically affecting versions prior to 1.8. This medium-severity flaw (CVSS 6.1) stems from improper use of add_query_arg() within the shibboleth_login_form function, allowing an unauthenticated attacker to inject malicious scripts via a network-based attack requiring user interaction. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the vulnerability could lead to information disclosure and data integrity issues.
