CVE-2025-14069 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Schema & Structured Data for WP & AMP plugin developed by magazine3 for WordPress. This vulnerability exists in all plugin versions up to and including 1.54. The root cause is insufficient sanitization and escaping of user-supplied input in the 'saswp_custom_schema_field' profile field, which is used to generate web pages with structured data. Authenticated attackers with Contributor-level access or higher can exploit this flaw by injecting arbitrary JavaScript code into this field. Because the injected scripts are stored persistently, they execute whenever any user accesses the affected page, potentially leading to session hijacking, unauthorized actions, or data theft. The vulnerability has a CVSS v3.1 base score of 6.4, reflecting medium severity, with an attack vector over the network, low attack complexity, requiring privileges, no user interaction, and a scope change. The impact affects confidentiality and integrity but not availability. No public exploits are known at this time, but the vulnerability poses a significant risk to WordPress sites using this plugin, especially those with multiple contributors. The plugin is widely used for enhancing SEO and structured data presentation, making it a valuable target for attackers aiming to compromise website visitors or administrators.

For European organizations, this vulnerability can lead to unauthorized script execution on their WordPress sites, compromising user data confidentiality and site integrity. Attackers could steal session cookies, perform actions on behalf of users, or deliver malicious payloads to site visitors, potentially damaging reputation and trust. Media companies, e-commerce platforms, and public-facing websites using this plugin are particularly at risk. The requirement for Contributor-level access means insider threats or compromised contributor accounts could be leveraged. Given the widespread use of WordPress in Europe, especially in countries with large digital economies, the impact could be significant if exploited at scale. Additionally, GDPR considerations mean that data breaches resulting from such attacks could lead to regulatory penalties and legal consequences.

1. Monitor for and apply security updates from the plugin vendor promptly once patches are released. 2. Until a patch is available, restrict Contributor-level access to trusted users only and review existing contributor accounts for suspicious activity. 3. Implement additional input validation and output encoding at the WordPress application or web server level to neutralize potentially malicious input in custom schema fields. 4. Employ Web Application Firewalls (WAFs) with rules targeting XSS payloads in HTTP requests related to the plugin's fields. 5. Conduct regular security audits and penetration testing focusing on user input fields in WordPress plugins. 6. Educate content contributors about the risks of injecting untrusted content and enforce strict content policies. 7. Consider disabling or replacing the plugin if immediate patching is not feasible and the risk is unacceptable.
