Contributor-level stored XSS via unescaped shortcode output
Published Jan 24, 2025 · Updated May 12, 2026
Stored XSS in Linnea Huxford Blur Text 1.0.0 and earlier allows remote authenticated users to inject scripts through shortcode content. The blur shortcode renders contributor-controlled content into page output without sufficient input sanitization or output escaping. Contributor-level access is required, and the stored script executes when a visitor loads the injected page, affecting that visitor's browser context.
