CVE-2026-2894 is a medium-severity information disclosure vulnerability affecting funadmin versions 7.1.0-rc1 through 7.1.0-rc4. The flaw resides in the getMember function located in the file app/frontend/view/login/forget.html. This function can be manipulated remotely without any authentication or user interaction, allowing attackers to retrieve sensitive information from the system. The vulnerability is exploitable over the network with low attack complexity and no privileges required, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) indicates partial impact on confidentiality with no effect on integrity or availability. Although no known exploits in the wild have been confirmed, publicly available exploit code exists, raising the likelihood of exploitation. The vendor was notified early but has not issued any response or patch, leaving systems exposed. The vulnerability could be leveraged to gather information that facilitates further attacks such as credential harvesting, privilege escalation, or targeted phishing. The lack of vendor remediation increases the urgency for organizations to implement compensating controls. Funadmin is a web-based administration framework, and this vulnerability affects its login-related functionality, which is a common attack vector. The absence of authentication requirements and user interaction makes this vulnerability particularly accessible to remote attackers.

The primary impact of CVE-2026-2894 is unauthorized disclosure of sensitive information, which can compromise confidentiality. This exposure can enable attackers to gather data useful for subsequent attacks, including identity theft, unauthorized access, or lateral movement within networks. Organizations relying on funadmin for administrative or user management functions may face increased risk of data breaches. Although the vulnerability does not directly affect system integrity or availability, the leaked information could facilitate more damaging exploits. The medium CVSS score reflects a moderate risk, but the availability of public exploits and lack of vendor response elevate the threat. For organizations with internet-facing funadmin instances, the risk of remote exploitation is significant. This can lead to reputational damage, regulatory penalties, and operational disruptions if sensitive user or system data is exposed. The absence of patches means organizations must rely on mitigation strategies until official fixes are released.

1. Immediately restrict external access to the affected getMember function and the forget.html endpoint by implementing network-level controls such as firewalls or web application firewalls (WAFs) with custom rules to block suspicious requests. 2. Monitor web server logs and application logs for unusual access patterns targeting the forget.html page or getMember function to detect potential exploitation attempts. 3. Employ rate limiting and IP reputation filtering to reduce the risk of automated attacks exploiting this vulnerability. 4. If possible, disable or temporarily remove the forget password functionality until a patch or official fix is available. 5. Regularly check for vendor updates or community patches addressing this vulnerability and apply them promptly once released. 6. Conduct internal audits to identify and secure any sensitive information that could be exposed through this vulnerability. 7. Educate system administrators and security teams about this vulnerability and ensure incident response plans include steps for potential exploitation scenarios. 8. Consider deploying application-layer encryption or tokenization for sensitive data to minimize the impact of information disclosure. 9. Use intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting funadmin components. 10. Engage with the funadmin community or security forums to share information and obtain any unofficial mitigations or workarounds.
