Vulnerability Overview

The bt_bb_get_grid AJAX action of the Bold Page Builder WordPress plugin before 3.1.6 passes user input into the unserialize() function without any validation or sanitisation, which could lead to a PHP Object Injection. Even though the plugin did not contain a suitable gadget to fully exploit the issue, other installed plugins on the blog could allow such issue to be exploited and lead to RCE in some cases.

Technical Analysis

REMEDIATION: Update to version 3.1.6, or a newer patched version --- IDENTIFIER: CWE-502 (Deserialization of Untrusted Data) The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
