CVE-2025-10978 is a medium-severity security vulnerability affecting JeecgBoot versions up to 3.8.2. The flaw resides in an unspecified function within the /sys/user/exportXls endpoint of the Filter Handler component. This vulnerability results in improper authorization, allowing an attacker to remotely exploit the system without requiring user interaction or elevated privileges. The CVSS 4.0 vector indicates that the attack can be performed over the network (AV:N) with low complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The impact on confidentiality is low, with no direct impact on integrity or availability. The vendor has not responded to disclosure attempts, and no patches or fixes have been released at the time of publication. Although no known exploits are currently active in the wild, a public exploit has been released, increasing the risk of exploitation. The vulnerability could allow unauthorized access to data exports via the exportXls function, potentially exposing sensitive user information or business data depending on the deployment context of JeecgBoot.

For European organizations using JeecgBoot, this vulnerability poses a risk of unauthorized data exposure through the exportXls functionality. Organizations in sectors handling sensitive or regulated data (e.g., finance, healthcare, government) could face compliance violations under GDPR if unauthorized data access occurs. The improper authorization flaw could be leveraged by remote attackers to access data exports without proper permissions, potentially leading to data leakage. Although the vulnerability does not directly affect system integrity or availability, the exposure of sensitive information could lead to reputational damage, regulatory fines, and loss of customer trust. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls. Since the exploit requires no user interaction and can be performed remotely, the attack surface is broad, especially for internet-facing deployments of JeecgBoot.

Given the absence of official patches, European organizations should implement the following specific mitigations: 1) Restrict network access to the /sys/user/exportXls endpoint by applying strict firewall rules or web application firewall (WAF) policies to limit access only to trusted internal IPs or VPN users. 2) Implement strong authentication and authorization checks at the application or proxy level to ensure only authorized users can invoke exportXls functionality. 3) Monitor and log all access attempts to the exportXls endpoint to detect anomalous or unauthorized usage patterns promptly. 4) If feasible, temporarily disable or remove the exportXls feature until a vendor patch is available. 5) Conduct a thorough audit of user permissions and data export policies within JeecgBoot to minimize data exposure risks. 6) Stay alert for vendor updates or community patches and apply them immediately upon release. 7) Educate IT and security teams about this vulnerability and the importance of monitoring related logs and alerts.
