The Blockspare plugin for WordPress has a security issue that allows hackers to inject harmful web scripts into pages. This can happen in versions 3.2.9 and below because the plugin does not properly clean or filter the input and output. This means that someone with contributor-level access or higher can insert dangerous code into a page, and it will run whenever a user visits that page.
