Input validation vulnerability in B Blocks – The ultimate block collection 2.0.0

  • Severity: medium-risk
  • Status: Fixed
  • Publication: April 4, 2025

The B Blocks plugin for WordPress, which is a collection of blocks, has a security issue known as Stored Cross-Site Scripting. This can affect versions up to 2.0.0 of the plugin because it does not properly filter and protect user input and output. This can allow attackers with contributor-level access or higher to insert harmful web scripts into pages that will run whenever someone visits that page.
