CVE-2025-62894 identifies a Stored Cross-site Scripting (XSS) vulnerability in the magicoders ACF Recent Posts Widget, a WordPress plugin used to display recent posts. The vulnerability stems from improper neutralization of input during web page generation, which allows malicious actors to inject arbitrary JavaScript code that is stored and later executed in the browsers of users viewing the affected widget. This vulnerability affects all versions up to and including 5.9.3. The CVSS 3.1 score is 5.4 (medium), with an attack vector of network (remote), low attack complexity, requiring low privileges and user interaction, and impacts confidentiality and integrity with no availability impact. Exploitation requires an authenticated user with at least low privileges to submit crafted input that the widget fails to sanitize properly. When other users load the widget, the malicious script executes in their context, potentially allowing session hijacking, credential theft, or content manipulation. Although no known exploits are currently in the wild, the vulnerability poses a risk especially in environments with multiple users or administrators. The vulnerability is significant because it affects a popular WordPress plugin, widely used across many websites, increasing the attack surface. The scope is limited to websites running the affected plugin versions, but the impact can be severe if exploited in high-value targets.

For European organizations, this vulnerability can lead to unauthorized access to user sessions, theft of sensitive information, and manipulation of website content, undermining user trust and potentially violating data protection regulations such as GDPR. Organizations relying on WordPress sites with the magicoders ACF Recent Posts Widget are at risk of targeted attacks, especially those with multiple authenticated users or administrators. The confidentiality and integrity of user data can be compromised, leading to reputational damage and potential legal consequences. Although availability is not directly impacted, the indirect effects of compromised user accounts or defaced content can disrupt business operations. The medium severity rating indicates a moderate risk, but the ease of exploitation by authenticated users and the potential for persistent malicious code execution make it a significant concern for organizations with public-facing websites or internal portals using this plugin.

1. Immediately update the magicoders ACF Recent Posts Widget plugin to a patched version once available. 2. If a patch is not yet available, restrict plugin usage to trusted users only and limit privileges to reduce the risk of malicious input. 3. Implement strict input validation and sanitization on all user inputs related to the widget, using server-side filtering to neutralize potentially malicious code. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Monitor web server and application logs for unusual input patterns or script injection attempts. 6. Educate users with access about the risks of injecting untrusted content and enforce strong authentication controls. 7. Consider using Web Application Firewalls (WAF) with rules to detect and block XSS payloads targeting this plugin. 8. Regularly audit WordPress plugins and themes for vulnerabilities and maintain an up-to-date inventory to quickly respond to new threats.
