CVE-2023-2735

Name of the Vulnerable Software and Affected Versions Groundhogg plugin for WordPress versions up to, and including, 2.7.9.8

Description The issue is related to Stored Cross-Site Scripting via the 'gh form' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. 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. The issue is specific to legacy contact forms.

Recommendations For Groundhogg plugin for WordPress versions up to, and including, 2.7.9.8, update to a version higher than 2.7.9.8 to resolve the issue. As a temporary workaround, consider restricting access to the 'gh form' shortcode for users with contributor-level and above permissions until a patch is available. Additionally, restrict the use of legacy contact forms to minimize the risk of exploitation.
