Deeper analysis

CVE-2026-27045 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the sb-woocommerce-infinite-scroll WordPress plugin, part of sbthemes WooCommerce Infinite Scroll. The flaw enables Object Injection and affects all versions from n/a through 1.6.2.

With a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), the vulnerability can be exploited by low-privileged authenticated users over the network with low attack complexity and no user interaction required. Successful exploitation allows attackers to achieve high impacts, including unauthorized access to sensitive data (C:H), modification of system resources (I:H), and denial of service (A:H), all within the unchanged scope.

Why these techniques?

PHP object injection via unsafe deserialization in a public-facing WordPress plugin directly enables exploitation of the web application (T1190) by low-privileged authenticated users, resulting in high-impact effects that facilitate privilege escalation to achieve full control (T1068).
