Administrator-targeted script execution via unescaped char parameter
Published Mar 13, 2025 · Updated Mar 14, 2025
Reflected XSS in Rivercitygraphix Limit Bio 1.0 and earlier allows remote attackers to execute scripts via a crafted char parameter. The public bio.php endpoint writes the char query parameter into the response without sanitization or output escaping. Exploitation requires a high-privilege user such as an administrator to follow a crafted link, after which the script runs in that user's browser context.
