The SKT Blocks – Gutenberg based Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Post Carousel block in all versions up to, and including, 1.9 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.

Note: Consider this fact that the EPSS model relies on historical data and real-world exploit information to calculate the probability of exploitation. When a CVE is newly published, there isn't enough data available to determine its likelihood of being exploited. As a result, the EPSS score defaults to 0 until more information becomes available.
