CVE-2025-13880 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the WP Social Ninja – Embed Social Feeds, Customer Reviews, Chat Widgets WordPress plugin developed by adreastrian. The vulnerability exists in all versions up to and including 4.0.1 due to the absence of proper capability checks in the getAdvanceSettings and saveAdvanceSettings functions. These functions handle the retrieval and modification of the plugin's advanced settings, which control how social feeds, user reviews, and chat widgets operate on WordPress sites. Because the plugin fails to verify whether the requester has the necessary permissions, unauthenticated attackers can remotely access these functions over the network without any user interaction or authentication. This allows attackers to both view sensitive configuration data and modify settings, potentially altering the behavior of embedded social feeds or chat widgets. The CVSS v3.1 base score is 6.5 (medium), reflecting the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality and integrity impacts (C:L, I:L). There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability poses risks primarily related to unauthorized disclosure and modification of plugin settings, which could be leveraged for further attacks or to undermine website trustworthiness.

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive plugin configuration data and unauthorized modification of social feed and chat widget settings on WordPress sites. This could result in altered or malicious content being displayed to site visitors, undermining user trust and potentially facilitating phishing or misinformation campaigns. Organizations relying on WP Social Ninja for customer engagement or social proof may experience reputational damage if attackers manipulate reviews or feeds. While the vulnerability does not directly impact availability, the integrity and confidentiality of site content and configuration are at risk. Given the ease of exploitation without authentication, attackers can target vulnerable sites en masse, increasing the risk of widespread impact. This is particularly concerning for European businesses with high web traffic, e-commerce platforms, or public sector websites that rely on WordPress and this plugin for customer interaction and marketing. The lack of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

1. Monitor the plugin vendor's official channels for the release of a security patch addressing CVE-2025-13880 and apply updates immediately upon availability. 2. Until a patch is released, restrict access to the WordPress admin and plugin endpoints by implementing IP whitelisting or web application firewall (WAF) rules to block unauthorized requests to the getAdvanceSettings and saveAdvanceSettings functions. 3. Employ strict role-based access controls (RBAC) within WordPress to limit which users can modify plugin settings, and audit user permissions regularly. 4. Enable detailed logging and monitoring of plugin-related API calls and administrative actions to detect suspicious activity indicative of exploitation attempts. 5. Consider temporarily disabling or removing the WP Social Ninja plugin if it is not critical to business operations, to eliminate the attack surface. 6. Educate web administrators and developers about this vulnerability to ensure rapid response and awareness. 7. Conduct regular security assessments of WordPress installations to identify and remediate similar authorization issues proactively.
