Base vector

AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: The SKT Blocks – Gutenberg based Page Builder plugin for WordPress versions up to, and including, 1.9

Description: The issue is related to Stored Cross-Site Scripting via the Post Carousel block due to insufficient input sanitization and output escaping. This allows 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.

Recommendations: For versions up to, and including, 1.9, update to a version that addresses the insufficient input sanitization and output escaping issue in the Post Carousel block to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the Post Carousel block for users with Contributor-level access and above until a patch is available.
