CVE-2025-6546Network attack vector

Contributor-level stored XSS via unescaped tablecssclass output

Published Jun 26, 2025 · Updated Apr 8, 2026

Stored cross-site scripting in azumbro Drive Folder Embedder 1.1.0 and earlier allows remote authenticated users to inject browser scripts. The tablecssclass parameter accepts insufficiently sanitized input, and the plugin embeds that value in page output without adequate escaping. Contributor-level access is required to store the payload, which executes when a user visits the affected page and can read or alter data available to that browser session.
