Subscriber-level stored XSS via unescaped id parameter
Published Apr 23, 2026 · Updated Apr 23, 2026
Stored XSS in Social Rocket – Social Sharing Plugin 1.3.4.2 and earlier allows remote authenticated users to inject scripts via the id parameter. The plugin accepts the id value without sufficient sanitization and later emits it into page output without escaping, preserving executable markup. Subscriber-level access is sufficient; the payload runs in a visitor's browser when an injected page is opened, enabling unauthorized page-context actions.
