CVSS v3.1
6.4
Medium
| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
The Essential Blocks – Page Builder Gutenberg Blocks, Patterns & Templates plugin for WordPress versions up to, and including, 5.3.1
Description
The issue is related to Stored Cross-Site Scripting via the Parallax slider due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page.
Recommendations
For versions up to, and including, 5.3.1, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the Parallax slider feature for users with Contributor-level access and above until a patch is available.
Fix
XSS
