Overview of CVE-2026-1923
A stored Cross-Site Scripting vulnerability affects the Social Rocket plugin. This flaw has a CVSS score of 6.4. It allows attackers to inject permanent scripts into your site. The scripts run automatically in every visitor’s browser. No clicks or interactions are required.
The Social Rocket plugin handles social sharing buttons and metadata. It accepts user input that it does not sanitize properly. This input gets stored and displayed to other users. Attackers exploit this to execute arbitrary JavaScript code.
Technical Details
The vulnerability exists in the plugin’s social sharing features. These features include custom share messages and social profile links. The plugin fails to escape HTML special characters in these fields. An attacker can submit malicious scripts through input forms.
The CVSS vector is AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N. The attack is network-based and has low complexity. It requires user interaction for the initial injection. But the stored script affects everyone else automatically. The confidentiality impact is high due to data theft potential.
The Social Rocket plugin runs on many WordPress sites. It is a popular choice for social media integration. This makes the vulnerability more impactful. Many websites are potentially affected.
Impact on Your Site
Attackers can steal cookies and session tokens from visitors. They can capture form submissions and login credentials. They can deface your website with malicious content. They can also redirect users to phishing pages.
The changed scope (S) in the CVSS vector makes this more severe. The attack affects resources beyond the plugin itself. It impacts the entire WordPress installation. An attacker who steals an admin session takes full control.
Your site visitors may not realize they are under attack. The malicious scripts run silently in the background. By the time you notice, the damage is already done. Regular security scans help detect such issues early.
