CVE-2018-18845 describes a reflected cross-site scripting (XSS) vulnerability in Advanced Comment System version 1.0, specifically within internal/advanced_comment_system/index.php and admin.php via the ACS_path parameter. This medium-severity vulnerability (CVSS 6.1) allows an unauthenticated remote attacker to inject malicious HTML or JavaScript, which is then executed in the victim's browser, potentially leading to information disclosure or session hijacking. While the product is discontinued and there is no evidence of active exploitation, nor publicly available exploit code or significant community discussion, the risk remains for unpatched, legacy deployments.
