CVE-2017-16043 describes a cross-site scripting (XSS) vulnerability in the Shout IRC client, affecting versions 0.44.0 through 0.49.3. The vulnerability arises because the /topic command in messages is unescaped, allowing attackers to inject malicious HTML scripts that execute in a victim's browser. With a CVSS score of 6.1 (Medium), this vulnerability requires user interaction (UI:R) and could lead to low confidentiality and integrity impacts (C:L, I:L). There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB, with minimal community discussion or media coverage.
