CVE-2025-67631 is a stored cross-site scripting (XSS) vulnerability identified in the Gift Hunt ecommerce platform, affecting versions up to and including 2.0.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently on the platform. When other users access the affected pages, the injected scripts execute in their browsers under the context of the vulnerable site. This can lead to a range of attacks including session hijacking, theft of cookies or credentials, defacement, or unauthorized actions performed on behalf of the victim user. Stored XSS is particularly dangerous because the malicious payload is saved on the server and served to multiple users, increasing the attack surface. No CVSS score is assigned yet, and no patches or known exploits are currently reported, indicating this is a newly disclosed vulnerability. The lack of authentication requirement for exploitation is not explicitly stated but typically stored XSS can be triggered by any user input fields that are not properly sanitized. The vulnerability affects ecommerce platforms, which are critical for online transactions and customer data management, increasing the risk of financial and reputational damage. The vulnerability was reserved and published in December 2025, with Patchstack as the assigner. The absence of official patches means organizations must implement interim mitigations and monitor for updates.

For European organizations, especially those operating ecommerce platforms or using Gift Hunt, this vulnerability poses significant risks. Exploitation could lead to compromise of customer accounts, theft of sensitive personal and payment information, and unauthorized transactions. The persistent nature of stored XSS means multiple users can be affected, amplifying the potential damage. This can result in loss of customer trust, regulatory penalties under GDPR for data breaches, and financial losses. The ecommerce sector in Europe is highly developed, with stringent data protection requirements, making the impact of such vulnerabilities more severe. Attackers could also leverage this vulnerability to pivot into broader network attacks or to distribute malware. The lack of known exploits currently reduces immediate risk but also means organizations must act proactively. The impact on availability is generally low, but integrity and confidentiality impacts are high. The vulnerability could affect customer-facing web applications, administrative interfaces, and third-party integrations within the ecommerce ecosystem.

Organizations should immediately review and enhance input validation and output encoding practices within Gift Hunt implementations. Employ context-aware output encoding (e.g., HTML entity encoding) to neutralize potentially malicious input before rendering it in web pages. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Conduct thorough code audits focusing on user input handling, especially in areas where user-generated content is displayed. Monitor web application logs and user reports for suspicious activity indicative of XSS exploitation attempts. Isolate or disable vulnerable features temporarily if feasible until official patches are released. Educate developers and administrators about secure coding practices related to XSS. Engage with the vendor or community to obtain or contribute to patches promptly. Use web application firewalls (WAFs) with updated rules to detect and block XSS payloads targeting Gift Hunt. Regularly update all components and dependencies of the ecommerce platform to minimize exposure to related vulnerabilities.
