AI Analysis
Technical Summary
CVE-2026-1826 is a stored cross-site scripting vulnerability in the OpenPOS Lite – Point of Sale for WooCommerce WordPress plugin. The issue occurs due to improper neutralization of input in the 'width' parameter of the order_qrcode shortcode, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 3.0 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).
Potential Impact
An attacker with Contributor-level or higher access can inject malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as theft of session tokens or manipulation of page content. There is no impact on availability. The vulnerability requires authenticated access and does not involve user interaction beyond viewing the injected page.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the order_qrcode shortcode. Monitor for updates from the vendor regarding patches or official mitigations.
