The vulnerability CVE-2025-26749 affects the WPFactory Additional Custom Product Tabs for WooCommerce plugin (version ≤ 1.7.0). It is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This flaw allows an attacker with low privileges to inject malicious scripts that are stored and later executed in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, low privileges required, user interaction required, and a scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker with low privileges to inject persistent malicious scripts that execute in the browsers of users who view the affected pages. This can lead to partial disclosure of information, modification of data, or disruption of service within the scope of the affected WooCommerce plugin. However, exploitation requires user interaction and low privileges, limiting the overall impact to medium severity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the affected plugin features and carefully validate or sanitize inputs where possible. Monitor vendor channels for updates and apply patches promptly once available.
