CVE-2026-3173, 28 May 2026
The Meta Field Block plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.5.1. This is due to the plugin allowing users to specify arbitrary object IDs and object types via block attributes without validating whether the authenticated user has permission to access the requested object's metadata. This makes it possible for authenticated attackers, with Contributor-level access and above, to read arbitrary user meta, post meta, and term meta data from any object in the database. On sites using plugins that store sensitive data in meta fields (e.g., WooCommerce billing/shipping information), this could lead to the exposure of Personally Identifiable Information (PII) including names, email addresses, phone numbers, and physical addresses. CVE record
CVE-2026-6252, 14 May 2026
The Meta Field Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tagName' block attribute in all versions up to, and including, 1.5.2 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.

What to do if you run Meta Field Block

If you run Meta Field Block, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.

If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
