Page Builder Gutenberg Blocks <= 3.1.16 - Authenticated (Contributor+) Stored Cross-Site Scripting via External iCal Feed Data

Page Builder Gutenberg Blocks <= 3.1.16 - Authenticated (Contributor+) Stored Cross-Site Scripting via External iCal Feed Data

The Page Builder Gutenberg Blocks – CoBlocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via external iCal feed data in all versions up to, and including, 3.1.16 due to insufficient output escaping of event titles, descriptions, and locations fetched from external iCal feeds in the Events block rendering function. 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.
Mögliche Gegenmaßnahme
Page Builder Gutenberg Blocks – CoBlocks: Update to version 3.1.17, or a newer patched version
