Technical Summary
CVE-2026-4730 is a stored cross-site scripting vulnerability in the Charts Ninja WordPress plugin (versions up to 2.1.0). The issue stems from improper neutralization of input in the 'chartid' shortcode attribute, 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 injected pages, potentially leading to information disclosure or session hijacking. The vulnerability is classified under CWE-79 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 access or higher can exploit this vulnerability to inject malicious scripts that execute in the browsers of users viewing the compromised pages. This can lead to limited confidentiality and integrity impacts, such as theft of user credentials or manipulation of page content. Availability is not affected. The vulnerability requires authentication and low attack complexity but affects all users accessing the injected content.
Mitigation Recommendations
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 removing or disabling the Charts Ninja plugin if feasible. Monitor for plugin updates from the vendor addressing this vulnerability.
