CVE-2025-11443 identifies an information exposure vulnerability in the JhumanJ OpnForm product, versions 1.9.0 through 1.9.3. The vulnerability resides in the Forgotten Password Handler component, specifically within the /api/password/email endpoint. This endpoint is responsible for initiating password reset requests. The flaw causes information exposure through a discrepancy, likely by revealing whether an email address is registered or not, or by leaking other sensitive information during the password reset process. The vulnerability can be exploited remotely without authentication or user interaction, but the attack complexity is high, making exploitation difficult. The CVSS 4.0 score is 6.3 (medium severity), reflecting the network attack vector, high complexity, no privileges required, and no user interaction needed. The vulnerability does not affect integrity or availability, only confidentiality (low impact). The issue is linked to a known Laravel framework vulnerability (issue #46465), which has led to no direct mitigation actions being taken by the vendor. No patches or fixes have been published yet, and no known exploits in the wild have been reported. The public availability of exploit code increases the risk of future exploitation. Organizations using affected versions of JhumanJ OpnForm should monitor for updates and consider compensating controls to limit information leakage during password reset flows.

For European organizations, the primary impact is the potential exposure of sensitive user information through the password reset functionality, which could facilitate user enumeration or targeted phishing attacks. This compromises confidentiality but does not directly affect system integrity or availability. Attackers could leverage exposed information to escalate attacks, such as credential stuffing or social engineering. Organizations handling sensitive or personal data are at higher risk of reputational damage and regulatory scrutiny under GDPR if user data is exposed. The high attack complexity and lack of known active exploitation reduce immediate risk but do not eliminate it, especially given the public availability of exploit code. The impact is more pronounced in sectors relying heavily on JhumanJ OpnForm for user authentication and password management, including financial services, healthcare, and government services within Europe.

Since no official patches or fixes are currently available, European organizations should implement compensating controls to mitigate the risk. These include: 1) Implement rate limiting and anomaly detection on the /api/password/email endpoint to prevent automated enumeration attempts. 2) Standardize password reset responses to avoid revealing whether an email address is registered, thus eliminating discrepancy-based information leaks. 3) Employ multi-factor authentication (MFA) to reduce the risk of account takeover even if user information is exposed. 4) Monitor logs for unusual password reset requests and investigate suspicious activity promptly. 5) Engage with the vendor and track updates related to Laravel issue #46465 and JhumanJ OpnForm patches. 6) Educate users about phishing risks associated with password reset processes. 7) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block exploitation attempts targeting this vulnerability.
