CVE-2026-57402 describes a stored cross-site scripting vulnerability in the wpdesk Flexible Refund and Return Order for WooCommerce plugin. The issue arises from improper neutralization of input during web page generation, allowing stored XSS attacks. The affected versions include all versions up to and including 1.0.51. The CVSS 3.1 vector indicates the attack requires network access, low attack complexity, low privileges, and user interaction, with impacts on confidentiality, integrity, and availability rated as low to low and low respectively. No official remediation or patch information is currently available.

Successful exploitation could allow an attacker with low privileges to inject malicious scripts that are stored and later executed in the context of users viewing affected pages. This can lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. However, the impact is rated medium severity due to the required user interaction and limited privileges needed.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting plugin usage or applying any recommended temporary mitigations from the vendor. Monitor vendor channels for updates and apply patches promptly once available.
