21
FAUCET Score

CVE-2025-63418 is a DOM-based Cross-Site Scripting (XSS) vulnerability in the SelfBest platform (version 2023.3) that allows attackers to execute arbitrary JavaScript within a logged-in user's session. This medium-severity vulnerability (CVSS 6.1) stems from inadequate client-side sanitization and a missing Content Security Policy, enabling injection via the browser's developer console. Successful exploitation could lead to account takeover and data theft. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
