CVE-2025-54749 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the Crocoblock JetProductGallery plugin up to version 2.2.0.2. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and store arbitrary scripts within the application. When a user accesses the affected page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability requires low privileges (PR:L) and user interaction (UI:R) to exploit, but it can impact confidentiality, integrity, and availability due to the scope of the stored XSS attack. The CVSS v3.1 score is 6.5 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), and scope changed (S:C), indicating that the vulnerability can affect components beyond the initially vulnerable module. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is particularly relevant for websites using JetProductGallery to display product images or galleries, commonly found in e-commerce or marketing sites built on WordPress or similar CMS platforms where Crocoblock plugins are popular.

For European organizations, this vulnerability poses a significant risk especially to e-commerce platforms, retail businesses, and any web services utilizing Crocoblock JetProductGallery. Exploitation could lead to data leakage of customer information, session hijacking, and unauthorized transactions, undermining customer trust and potentially violating GDPR requirements regarding data protection and breach notification. The stored XSS nature means that multiple users can be affected once the malicious payload is stored and served, amplifying the impact. Additionally, the scope change in the CVSS vector suggests that the vulnerability might allow attackers to escalate their privileges or affect other components, increasing the risk of broader compromise. Organizations relying on this plugin without timely updates or mitigations could face reputational damage, financial losses, and regulatory penalties.

1. Immediate auditing of all instances of JetProductGallery plugin usage within the organization’s web infrastructure to identify affected versions. 2. Since no official patches are linked yet, implement Web Application Firewall (WAF) rules to detect and block typical XSS payloads targeting the plugin’s input fields. 3. Employ Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of potential XSS payloads. 4. Sanitize and validate all user inputs rigorously on both client and server sides, especially inputs that are rendered in product galleries or related components. 5. Monitor logs and user reports for unusual behavior indicative of XSS exploitation attempts. 6. Prepare for rapid deployment of patches once released by Crocoblock and test updates in staging environments before production rollout. 7. Educate web developers and administrators about secure coding practices related to input handling and output encoding to prevent similar vulnerabilities.
