CVE-2025-58797 Overview
CVE-2025-58797 is a sensitive data exposure vulnerability in the Ninja Charts WordPress plugin developed by Mahmudul Hasan Arif. The flaw affects all versions up to and including 3.3.5. It falls under [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere. Unauthenticated remote attackers can retrieve embedded sensitive data from vulnerable WordPress sites over the network without user interaction. The issue carries a CVSS 3.1 base score of 5.3, reflecting a confidentiality impact without integrity or availability consequences.
Critical Impact
Unauthenticated network attackers can retrieve embedded sensitive data from Ninja Charts installations, potentially exposing information used in dashboards, reports, or connected data sources.
Affected Products
- Ninja Charts plugin for WordPress (ninja-charts)
- All versions up to and including 3.3.5
- WordPress sites using Ninja Charts to render embedded data visualizations

Technical Details for CVE-2025-58797
Vulnerability Analysis
The Ninja Charts plugin exposes sensitive system information to actors outside the intended control sphere. The plugin embeds data used to render charts, and this data is accessible to unauthorized requesters. The Common Weakness Enumeration classifies this pattern as [CWE-497], where an application inadvertently reveals internal state or configuration to unprivileged callers.
The attack requires no authentication and no user interaction. An unauthenticated remote actor can query the affected endpoints and retrieve chart-embedded content the site owner intended to keep restricted. The EPSS probability sits at 0.285%, indicating limited public exploitation activity to date.
Root Cause
The root cause is missing authorization on plugin endpoints that return chart data. Ninja Charts stores information used to populate visualizations, including values that may originate from private database queries or connected data sources. The plugin fails to enforce capability checks before returning that data, allowing anonymous callers to receive content that should be restricted to authorized users.
Attack Vector
An attacker sends network requests to the plugin's data-serving endpoints on a target WordPress site. Because the endpoints do not validate the caller's identity or privileges, the response includes embedded sensitive data. No credentials, tokens, or session state are required. The attacker aggregates responses to reconstruct dashboards, source values, or metadata that the site did not intend to publish. Technical specifics are documented in the Patchstack Vulnerability Report.
Detection Methods for CVE-2025-58797
Indicators of Compromise
- Unauthenticated HTTP GET or POST requests to Ninja Charts REST or AJAX endpoints from external IP addresses
- Elevated traffic volumes to /wp-json/ or admin-ajax.php paths referencing ninja-charts or ninja_charts actions
- Repeated enumeration of numeric chart identifiers in access logs
Detection Strategies
- Review web server logs for anonymous requests targeting Ninja Charts endpoints and correlate with response sizes indicating data payloads
- Deploy WordPress security plugins or a WAF ruleset that flags unauthenticated access to plugin AJAX and REST routes
- Compare installed Ninja Charts version against 3.3.5 across managed WordPress sites and inventory exposed instances
Monitoring Recommendations
- Alert on spikes in outbound response bytes from admin-ajax.php correlated with ninja-charts action parameters
- Track referer and user-agent patterns for scripted enumeration of chart IDs
- Monitor Patchstack and NVD feeds for updated advisories referencing CVE-2025-58797
How to Mitigate CVE-2025-58797
Immediate Actions Required
- Update the Ninja Charts plugin to a version later than 3.3.5 once the vendor releases a fix
- Audit existing charts for embedded sensitive values and rotate any credentials, tokens, or identifiers that may have been exposed
- Restrict public access to WordPress AJAX and REST endpoints associated with Ninja Charts using a web application firewall
Patch Information
At the time of publication, the advisory covers Ninja Charts through version 3.3.5. Administrators should consult the Patchstack Vulnerability Report and the WordPress plugin repository for the fixed release. Apply the patched version across all managed WordPress sites and confirm the update via the plugin management console.
Workarounds
- Deactivate and remove the Ninja Charts plugin until a patched version is installed if charts contain sensitive data
- Block unauthenticated access to Ninja Charts endpoints at the WAF or reverse proxy layer
- Remove sensitive values from existing charts and reconfigure data sources to avoid embedding confidential fields
