Technical Analysis

CVE-2025-31045 is a high-severity vulnerability classified under CWE-497, which pertains to the exposure of sensitive system information to an unauthorized control sphere. This vulnerability affects the elfsight Contact Form widget, specifically versions up to 2.3.1. The flaw allows an attacker to retrieve embedded sensitive data from the widget without requiring any authentication or user interaction. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the vulnerability is remotely exploitable over the network with low attack complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, with high confidentiality impact but no effect on integrity or availability. The vulnerability likely stems from improper handling or exposure of sensitive configuration or system information within the widget, which could include API keys, credentials, or other sensitive embedded data. Although no known exploits are currently reported in the wild, the ease of exploitation and the nature of the exposed data make this a significant risk. The absence of a patch link indicates that a fix may not yet be publicly available, increasing the urgency for mitigation. Organizations using the elfsight Contact Form widget should consider this vulnerability critical to address due to the potential for data leakage that could facilitate further attacks or unauthorized access.

Potential Impact

For European organizations, this vulnerability poses a substantial risk to the confidentiality of sensitive information handled by websites or applications using the elfsight Contact Form widget. Exposure of embedded sensitive data could lead to unauthorized access to backend systems, compromise of user data, or leakage of credentials that attackers could leverage for lateral movement or further exploitation. Given the widget's role in collecting user input, the breach of embedded secrets might also undermine trust and compliance with data protection regulations such as GDPR. The impact is particularly critical for sectors handling sensitive personal data, including finance, healthcare, and government services. Additionally, the vulnerability's remote exploitability without authentication increases the attack surface, making it easier for threat actors to target European organizations that rely on this widget for customer interaction or lead generation. The lack of known exploits in the wild currently provides a limited window for proactive defense, but the high CVSS score suggests that exploitation could have severe consequences if weaponized.

Mitigation Recommendations

1. Immediate mitigation should include removing or disabling the elfsight Contact Form widget from public-facing websites until a patch or update is available. 2. Monitor official elfsight channels for security advisories or patches addressing CVE-2025-31045 and apply updates promptly once released. 3. Conduct a thorough audit of all instances of the widget to identify any exposed sensitive data and rotate any potentially compromised credentials or API keys. 4. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the widget's endpoints. 5. Employ network segmentation and strict access controls to limit the impact of any data exposure. 6. Review and enhance logging and monitoring to detect anomalous access patterns that may indicate exploitation attempts. 7. Educate development and security teams about the risks of embedding sensitive data in client-side components and enforce secure coding practices to prevent similar issues in the future.
