CVE-2025-14298 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79 found in the FiboSearch – Ajax Search for WooCommerce plugin for WordPress. The vulnerability exists in all versions up to and including 1.32.0 due to insufficient sanitization and output escaping of user-supplied attributes in the plugin's 'thegem_te_search' shortcode. This shortcode is specifically used when the premium TheGem WordPress theme is installed with Header Builder mode enabled and the FiboSearch plugin's 'Replace search bars' option is activated for TheGem integration. An attacker with authenticated Contributor-level access or higher can inject arbitrary JavaScript payloads into pages via this shortcode. These scripts are stored and executed in the context of any user who views the affected page, potentially leading to session hijacking, privilege escalation, or data theft. The vulnerability requires authentication and user interaction, limiting its exploitation scope but still posing a significant risk in multi-user environments. The CVSS v3.1 base score is 5.4, reflecting network attack vector, low attack complexity, privileges required, user interaction needed, and partial confidentiality and integrity impact but no availability impact. No public exploits have been reported yet, but the vulnerability is published and should be addressed promptly. The flaw arises from improper neutralization of input during web page generation, a common issue in web applications that handle dynamic content. The plugin is widely used in WooCommerce-based e-commerce sites, making this a relevant threat to online retailers using WordPress. The combination with TheGem theme's specific features is a prerequisite, narrowing the affected user base but still significant given the popularity of both products.

For European organizations, especially those operating e-commerce platforms on WordPress with WooCommerce, this vulnerability can lead to unauthorized script execution in users' browsers. This compromises confidentiality by potentially exposing session cookies, personal data, or administrative credentials. Integrity may be impacted if attackers manipulate page content or perform actions on behalf of users. Although availability is not directly affected, the reputational damage and potential regulatory consequences under GDPR for data breaches can be severe. The requirement for Contributor-level access means insider threats or compromised accounts can be leveraged. The vulnerability's reliance on TheGem theme integration limits exposure but does not eliminate risk for organizations using this popular premium theme. Attackers could use this vector to conduct phishing, spread malware, or pivot to further attacks within the network. Given the medium CVSS score, the threat is moderate but should not be underestimated in environments with multiple users and sensitive data. European e-commerce businesses are particularly vulnerable due to the widespread use of WooCommerce and WordPress, making this a relevant concern for maintaining secure online storefronts and customer trust.

1. Monitor for and apply updates to the FiboSearch – Ajax Search for WooCommerce plugin as soon as a security patch addressing CVE-2025-14298 is released. 2. Temporarily disable the 'thegem_te_search' shortcode or the FiboSearch 'Replace search bars' option for TheGem integration if patching is not immediately possible. 3. Restrict Contributor-level permissions strictly, auditing user roles to ensure only trusted users have such access. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns related to the shortcode parameters. 5. Conduct regular security reviews of installed plugins and themes, focusing on those with known vulnerabilities or complex integrations. 6. Educate site administrators and content contributors about the risks of XSS and safe content practices. 7. Use Content Security Policy (CSP) headers to limit the impact of injected scripts by restricting allowed script sources. 8. Monitor logs and user activity for unusual behavior that might indicate exploitation attempts. 9. Consider isolating or sandboxing user-generated content areas to minimize script execution risks. 10. Backup site data regularly to enable recovery in case of compromise.
