The Display custom fields in the frontend – Post and User Profile Fields plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.1 via the vg_display_data shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve potentially sensitive post meta.

The Display custom fields in the frontend – Post and User Profile Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode and postmeta in all versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for 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 Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a custom text field in all versions up to, and including, 6.2.4 due to insufficient input sanitization and output escaping. 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.

The Calculated Fields Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's CP_CALCULATED_FIELDS shortcode in all versions up to, and including, 1.2.52 due to insufficient input sanitization and output escaping on user supplied 'location' attribute. This makes it possible for 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 Calculated Fields Form WordPress plugin before 1.1.151 does not sanitise and escape some of its form settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

The Calculated Fields Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.2.40 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The LinkedCustomFields plugin for MantisBT allows users to link values between two custom fields, creating linked drop-downs. Prior to version 2.0.1, cross-site scripting in the MantisBT LinkedCustomFields plugin allows Javascript execution, when a crafted Custom Field is linked via the plugin and displayed when reporting a new Issue or editing an existing one. This issue is fixed in version 2.0.1. As a workaround, one may utilize MantisBT's default Content Security Policy, which blocks script execution.
