CVE-2025-12705 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Social Reviews & Recommendations plugin for WordPress, specifically the widgetpack Reviews Widget that integrates Google, Yelp, and other recommendation reviews. The vulnerability stems from improper neutralization of input during web page generation, classified under CWE-79. The root cause lies in insufficient input sanitization and output escaping within the 'trim_text' function, which processes user-supplied parameters. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into pages that display user reviews. When legitimate users access these pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The vulnerability affects all plugin versions up to and including 2.5, with a partial patch applied in version 2.5, indicating that earlier versions remain fully vulnerable. The CVSS 3.1 base score is 7.2, reflecting a high severity due to network attack vector, no required privileges or user interaction, and a scope change impacting confidentiality and integrity. No known exploits are currently reported in the wild, but the ease of exploitation and impact make it a significant risk. The plugin is widely used on WordPress sites to display aggregated reviews, making many websites potential targets. The vulnerability's exploitation can compromise the trustworthiness of review content and the security of site visitors.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of user data and website content. Organizations relying on the affected plugin to display customer reviews on their websites may face session hijacking, theft of authentication tokens, or redirection of users to malicious sites, damaging brand reputation and customer trust. The vulnerability can also facilitate further attacks such as phishing or malware distribution. E-commerce platforms, service providers, and businesses that heavily depend on online reviews for customer engagement are particularly vulnerable. Additionally, regulatory compliance risks arise under GDPR if personal data is compromised due to exploitation. The availability impact is minimal, but the breach of confidentiality and integrity can have severe operational and financial consequences. The fact that exploitation requires no authentication or user interaction increases the threat level, making automated attacks feasible. The partial patch in version 2.5 means organizations running older versions remain exposed, and incomplete remediation may still leave residual risks.

1. Immediately update the Social Reviews & Recommendations plugin to the latest version beyond 2.5 that fully addresses the vulnerability. 2. If an update is not immediately possible, apply manual input validation and output encoding on all user-supplied data processed by the 'trim_text' function or equivalent areas. 3. Employ Web Application Firewalls (WAFs) with rules designed to detect and block common XSS payloads targeting this plugin. 4. Conduct thorough code reviews and penetration testing focusing on user input handling in review widgets. 5. Monitor web server logs and user reports for signs of suspicious script injections or anomalous behavior. 6. Educate web administrators and developers about secure coding practices, especially regarding input sanitization and output escaping. 7. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. 8. Regularly audit all third-party plugins and dependencies for vulnerabilities and timely patching. 9. Consider isolating or disabling the vulnerable widget temporarily if immediate patching is not feasible. 10. Maintain backups and incident response plans to quickly recover from potential exploitation.
