CVE-2026-4059 is a stored cross-site scripting vulnerability in the ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin for WordPress. It affects all versions up to and including 3.3.5. The vulnerability is due to improper neutralization of input in the button_text attribute of the woolentor_quickview_button shortcode, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to session hijacking or other client-side impacts. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial confidentiality and integrity impact.

An authenticated attacker with Contributor-level access or higher can inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to partial confidentiality and integrity loss, such as theft of session tokens or manipulation of page content. There is no impact on availability. No known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the woolentor_quickview_button shortcode.
