CVE-2024-1691 is a vulnerability found in the Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE PRO plugin for WordPress. This vulnerability, present in versions up to and including 2.6.3, allows for Stored Cross-Site Scripting via file upload form, specifically allowing SVG uploads.
