The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'no_data_msg' Shortcode Attribute in all versions up to, and including, 3.3.60 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Although wp_kses_post is applied to post content on save, it only strips HTML tokens and does not neutralize C-style escape sequences embedded within shortcode attribute values, meaning contributors can craft a payload that survives the kses filter and is silently reconstructed into a raw script tag at render time.
AnalysisAI
Stored Cross-Site Scripting in the WordPress Download Manager plugin (all versions through 3.3.60) allows authenticated contributors to persistently inject arbitrary JavaScript via the no_data_msg shortcode attribute, executing in any subsequent visitor's browser context. The vulnerability exploits a bypass in WordPress's wp_kses_post sanitization: the filter strips disallowed HTML tokens at save time but does not neutralize C-style escape sequences embedded in shortcode attribute values, which are silently reconstructed into raw <script> tags at render time. …
