What is CVE-2024-1691?

The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE PRO plugin for WordPress has a vulnerability that allows unauthenticated attackers to exploit a stored cross-site scripting flaw via an insecure file upload form. This issue arises from insufficient input sanitization and output escaping, specifically when handling SVG file uploads. Attackers can inject malicious scripts into pages, which will execute whenever a user visits the compromised page. While version 2.6.4 addresses this issue by sanitizing uploaded SVG files, earlier versions remain vulnerable.
