CVE-2025-11442 identifies a Cross-Site Request Forgery vulnerability in JhumanJ OpnForm versions 1.9.0 through 1.9.3. The vulnerability resides in an unspecified function within the product's API endpoint, which can be manipulated remotely to perform unauthorized actions on behalf of an authenticated user. Unlike traditional CSRF attacks that exploit the victim's browser session, this vulnerability requires the attacker to possess a valid JSON Web Token (JWT) bearer token used for API authentication. The vendor has stated that API calls require such tokens, and classic CSRF attacks without token possession are ineffective. Additionally, previous attack vectors such as Cross-Site Scripting (XSS), which could have been used to steal JWTs, have been mitigated, further reducing the attack surface. The vulnerability has a CVSS 4.0 score of 5.3, indicating medium severity, with attack vector being network-based, low attack complexity, no privileges required, but requiring user interaction and resulting in low integrity impact. No patches or exploit code have been publicly released, and no active exploitation has been reported. The vulnerability highlights the importance of secure token management and API endpoint protections in modern web applications.

For European organizations using JhumanJ OpnForm versions up to 1.9.3, this vulnerability could allow remote attackers to perform unauthorized API actions if they manage to obtain a valid JWT bearer token. While the direct risk is mitigated by the requirement of token possession and the absence of known exploits, the potential impact includes unauthorized data manipulation or service disruption through API misuse. Confidentiality impact is minimal since the attacker must already have token access, but integrity could be compromised if unauthorized API calls modify data or system state. Availability impact is negligible. The medium severity rating reflects the limited scope and complexity of exploitation. Organizations relying on OpnForm for critical workflows should consider this vulnerability in their risk assessments, especially if token security or session management is weak. The lack of known active exploits reduces immediate risk but does not eliminate the need for vigilance.

European organizations should implement strict JWT token management policies, including short token lifetimes, secure storage, and regular token rotation to minimize the risk of token theft. Employing additional API security measures such as mutual TLS authentication, IP whitelisting, or rate limiting can further reduce attack surface. Monitoring API usage logs for anomalous or unauthorized requests can help detect exploitation attempts early. Since no official patches are currently available, organizations should consider upgrading to versions beyond 1.9.3 if future releases address this issue or apply custom mitigations such as validating the origin of API requests and enforcing stricter CSRF protections at the application layer. Conducting security audits and penetration testing focused on token handling and API endpoint security is recommended. Finally, educating developers and administrators about secure token practices and the limitations of CSRF protections in token-based authentication contexts is essential.
