CVE-2023-6694

Name of the Vulnerable Software and Affected Versions Beaver Themer plugin for WordPress versions up to, and including, 1.4.9

Description The issue is related to Stored Cross-Site Scripting via the plugin's shortcode(s) due to insufficient input sanitization and output escaping on user-supplied custom fields. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 1.4.9, update to a version later than 1.4.9 to resolve the issue. As a temporary workaround, consider restricting access to the plugin's shortcode(s) to minimize the risk of exploitation. Additionally, restrict permissions to prevent authenticated attackers with contributor-level and above permissions from injecting arbitrary web scripts.
