CVE-2025-5564: 
WordPress vulnerability analysis and mitigation

The GC Social Wall plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2025-5564) discovered on June 25, 2025. This vulnerability affects all versions up to and including 1.15 of the plugin, stemming from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'gcsocialwall' shortcode (NVD CVE, Wiz).

The vulnerability is classified as a Cross-Site Scripting (CWE-79) issue with a CVSS v3.1 Base Score of 6.4 (Medium). The attack vector is characterized as CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, indicating network accessibility, low attack complexity, required low privileges, no user interaction, and potential for confidentiality and integrity impacts (Wordfence).

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page, potentially leading to unauthorized data access or manipulation of user sessions (NVD CVE).

Users should update the GC Social Wall plugin to a version newer than 1.15 once available. Until then, site administrators should carefully review and potentially restrict access to users with contributor-level permissions to minimize the risk of exploitation (NVD CVE).
