CVE-2025-58797 is a medium-severity vulnerability classified under CWE-497, which pertains to the exposure of sensitive system information to an unauthorized control sphere. This vulnerability affects the Ninja Charts plugin developed by Mahmudul Hasan Arif, specifically versions up to 3.3.2. The issue allows an attacker to retrieve embedded sensitive data without requiring any authentication or user interaction. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), the vulnerability is remotely exploitable over the network with low attack complexity, no privileges, and no user interaction needed. The impact is limited to confidentiality, with no effect on integrity or availability. The vulnerability does not have any known exploits in the wild as of the publication date (September 5, 2025), and no patches have been released yet. The lack of a patch increases the urgency for organizations using this plugin to implement mitigations. Ninja Charts is a WordPress plugin used for creating interactive charts and visualizations, often embedded in websites to display data. The exposure of sensitive system information could include configuration details, API keys, or other embedded secrets that could facilitate further attacks or data breaches if accessed by unauthorized parties. Since the vulnerability is exploitable remotely without authentication, it poses a risk to any publicly accessible WordPress site using the affected versions of Ninja Charts.

For European organizations, the exposure of sensitive information through this vulnerability could lead to unauthorized disclosure of confidential data, potentially including internal system details or credentials embedded within the plugin. This could facilitate lateral movement or targeted attacks against the affected organizations. Given the widespread use of WordPress across Europe, including by SMEs, public sector entities, and enterprises, the vulnerability could have broad implications. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, may face compliance risks if sensitive data is exposed. Although the vulnerability does not directly impact system integrity or availability, the confidentiality breach could undermine trust, lead to reputational damage, and trigger regulatory scrutiny under GDPR. The absence of known exploits reduces immediate risk, but the ease of exploitation and lack of authentication requirements mean attackers could quickly develop exploits once the vulnerability becomes widely known.

1. Immediate mitigation should include auditing all WordPress sites for the presence of Ninja Charts plugin and identifying the version in use. 2. Until an official patch is released, restrict access to the affected plugin files and endpoints using web application firewalls (WAFs) or server-level access controls to block unauthorized requests targeting Ninja Charts resources. 3. Implement network-level restrictions such as IP whitelisting or geo-blocking where feasible to limit exposure. 4. Monitor web server logs and intrusion detection systems for unusual access patterns or attempts to retrieve sensitive data from Ninja Charts components. 5. Review and rotate any sensitive credentials or API keys that may be embedded within the plugin or its configuration to minimize the impact of potential data exposure. 6. Plan for prompt patching once a fix is available, including testing in staging environments to ensure compatibility and security. 7. Educate site administrators about the risks and encourage regular plugin updates and security best practices. 8. Consider alternative charting plugins with a strong security track record if immediate patching is not possible.
