CVE-2026-2052

What is known

The Widget Options – Advanced Conditional Visibility for Gutenberg Blocks & Classic Widgets plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.2.2 via the Display Logic feature. This is due to the plugin using eval() on user-supplied Display Logic expressions with an insufficient blocklist/allowlist that can be bypassed using array_map with string concatenation, combined with a lack of authorization enforcement on the extended_widget_opts_block attribute. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server. The vulnerability was partially patched in version 4.2.0.

Business impact

Successful exploitation of CVE-2026-2052, a high vulnerability (CVSS 8.8) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
