CVE-2024-3344

Name of the Vulnerable Software and Affected Versions The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress versions up to, and including, 2.6.8

Description The issue is related to Stored Cross-Site Scripting via SVG file upload due to insufficient input sanitization and output escaping. This allows authenticated attackers with author-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, 2.6.8, update to a version higher than 2.6.8 to resolve the issue. As a temporary workaround, consider restricting access to the SVG file upload feature to minimize the risk of exploitation. Additionally, restrict access to pages that may have been injected with malicious scripts to prevent their execution.
