Reflected XSS via unescaped URL attributes
Published Apr 17, 2023 · Updated Feb 6, 2025
Reflected XSS in Shazzad Hossain Khan W4 Post List before 2.4.6 allows remote attackers to execute script via crafted URLs. The plugin places attacker-controlled URL text into HTML attributes without contextual escaping in documentation and list-navigation output. Exploitation requires a victim to open a crafted URL and, for the documentation path, an authenticated administrator; injected script executes in the site's browser origin and can read or alter page data.
