漏洞标题
Content Blocks (Custom Post Widget) <= 3.3.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via content Parameter
漏洞描述信息
The Content Blocks (Custom Post Widget) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘content’ parameter within the plugin's shortcode Content Block in all versions up to, and including, 3.3.5 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.
