CVE-2025-10130 is a stored Cross-Site Scripting vulnerability identified in the Layers plugin for WordPress, developed by stripeswp. The vulnerability exists in all versions up to and including 0.5, specifically in the handling of the 'webcam' shortcode. The root cause is insufficient sanitization and output escaping of user-supplied attributes within this shortcode, which allows an authenticated attacker with contributor-level or higher privileges to inject arbitrary JavaScript code into pages. When any user accesses a page containing the injected script, the malicious code executes in their browser context. This can lead to a range of attacks including session hijacking, privilege escalation, defacement, or distribution of malware. The vulnerability requires authentication but no user interaction beyond viewing the affected page. The CVSS 3.1 base score is 6.4, reflecting medium severity with network attack vector, low attack complexity, and partial impact on confidentiality and integrity but no impact on availability. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and assigned by Wordfence. The scope is limited to WordPress sites using the Layers plugin with the vulnerable shortcode enabled and contributor-level users able to add or modify content. This vulnerability highlights the importance of proper input validation and output encoding in web applications, especially in CMS plugins that accept user-generated content.

For European organizations, this vulnerability poses a moderate risk primarily to websites running WordPress with the Layers plugin installed. The ability for contributors to inject persistent malicious scripts can lead to unauthorized access to user sessions, theft of sensitive data, or defacement of public-facing websites. This can damage organizational reputation, lead to data breaches, and potentially facilitate further attacks within the network. Sectors with high reliance on WordPress for public communication, such as media, education, and small to medium enterprises, are particularly vulnerable. The requirement for contributor-level access limits the risk to organizations with lax user permission controls or those that allow external contributors. However, given the widespread use of WordPress across Europe and the popularity of plugins, the attack surface is significant. The vulnerability does not impact availability but can compromise confidentiality and integrity of web content and user data. Regulatory implications under GDPR may arise if personal data is compromised through this vector.

1. Immediately audit WordPress installations to identify the presence of the Layers plugin and determine the version in use. 2. Restrict contributor-level permissions to trusted users only and review user roles to minimize unnecessary privileges. 3. Until an official patch is released, disable or remove the 'webcam' shortcode functionality if possible to prevent exploitation. 4. Employ Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads, especially targeting the plugin's shortcode parameters. 5. Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites. 6. Monitor logs and user activity for suspicious content creation or modification indicative of exploitation attempts. 7. Once a patch or update is available from stripeswp, apply it promptly and verify the fix. 8. Educate content contributors about the risks of injecting untrusted content and enforce secure content creation policies. 9. Conduct regular vulnerability scanning and penetration testing focused on CMS plugins and user input handling. 10. Backup website data regularly to enable quick restoration in case of compromise.
