CVE-2018-20595 describes a Cross-Site Request Forgery (CSRF) vulnerability in hsweb version 3.0.4, specifically within the OAuth2 client controller. This high-severity flaw, rated 8.8 CVSSv3, stems from the application failing to validate the "state" parameter between the request and session after successful user authentication.

There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
