CVE-2025-13880 is a vulnerability identified in the WP Social Ninja plugin for WordPress, which integrates social feeds, customer reviews, and chat widgets into websites. The vulnerability stems from a missing authorization check (CWE-862) in two critical functions: getAdvanceSettings and saveAdvanceSettings. These functions handle the retrieval and modification of the plugin's advanced settings. Because the plugin fails to verify user capabilities before executing these functions, unauthenticated attackers can remotely access and alter sensitive configuration data without any authentication or user interaction. This flaw affects all versions up to and including 4.0.1. The vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), with impacts on confidentiality and integrity but not availability. Although no known exploits have been reported in the wild, the ease of exploitation and the potential to manipulate plugin settings pose risks such as unauthorized data disclosure, configuration tampering, and potential downstream impacts on site functionality or data integrity. The absence of a patch at the time of reporting necessitates immediate attention to access controls and monitoring.

For European organizations, the vulnerability could lead to unauthorized exposure and modification of plugin settings, potentially undermining the integrity of social feeds, customer reviews, and chat widgets displayed on their websites. This could damage brand reputation, erode customer trust, and possibly facilitate further attacks if attackers manipulate settings to inject malicious content or disrupt services. Organizations relying heavily on WordPress for e-commerce, media, or customer engagement platforms are particularly vulnerable. The confidentiality impact is moderate as attackers can view sensitive configuration data, and integrity impact is also moderate due to the ability to alter settings. Availability is not affected directly. The risk is heightened in sectors where customer feedback and social proof are critical, such as retail, hospitality, and online services. Additionally, regulatory compliance concerns may arise if unauthorized data disclosure occurs, especially under GDPR requirements.

Until an official patch is released, organizations should implement strict access controls at the web server or application firewall level to restrict access to the plugin's advanced settings endpoints. Monitoring web server logs for unusual access patterns targeting getAdvanceSettings and saveAdvanceSettings functions is advised. Employing a Web Application Firewall (WAF) with custom rules to block unauthorized requests to these functions can reduce exposure. Administrators should audit user roles and permissions within WordPress to ensure that only trusted users have access to plugin management interfaces. Regular backups of plugin configurations should be maintained to enable quick restoration if unauthorized changes occur. Once a patch is available, immediate updating of the plugin is critical. Additionally, organizations should consider isolating WordPress instances hosting critical customer-facing plugins and applying network segmentation to limit exposure. Security awareness training for site administrators on plugin management best practices can further reduce risk.
