CVE-2026-5848: Code Injection in JimuReport 2.0.0-2.3.0
Platform
java
Component
jeecgboot-jimureport
Fixed in
2.0.1
2.1.1
2.2.1
2.3.1
CVE-2026-5848 describes a code injection vulnerability discovered in JimuReport, a reporting tool, affecting versions 2.0.0 through 2.3.0. An attacker can exploit this flaw by manipulating the dbUrl parameter within the /drag/onlDragDataSource/testConnection file, potentially leading to remote code execution. The vendor has acknowledged the issue and plans to release a patch in a future update. Exploitation is currently possible due to the public availability of a proof-of-concept.

Impact and Attack Scenarios
Successful exploitation of CVE-2026-5848 allows an attacker to inject and execute arbitrary code on the JimuReport server. This could lead to complete system compromise, including data exfiltration, modification, or deletion. The attacker could potentially gain control of the underlying database, access sensitive reports, and pivot to other systems on the network. Given the remote nature of the vulnerability and the availability of a public exploit, the blast radius is significant, potentially impacting all systems running vulnerable versions of JimuReport. The ability to inject code via a database connection parameter is a concerning pattern, similar to vulnerabilities that have previously allowed attackers to bypass authentication and gain privileged access.
Exploitation Context
CVE-2026-5848 is currently considered a high-priority vulnerability due to the public availability of a proof-of-concept exploit. While it is not yet listed on CISA KEV, its ease of exploitation and potential impact suggest it could be added in the future. The vulnerability was publicly disclosed on 2026-04-09, indicating a relatively short timeframe between discovery and public awareness. Active exploitation is likely, and organizations should prioritize remediation.

What do these metrics mean?
- Attack Vector
- Network — remotely exploitable over the internet. No physical or local access required. Widest attack surface.
- Attack Complexity
- Low — no special conditions required. Attacker can exploit reliably without depending on rare configurations or timing.
- Privileges Required
- High — admin or privileged account required to exploit.
- User Interaction
- None — attack is automatic and silent. Victim does nothing: no click, no file open.
- Scope
- Unchanged — impact is limited to the vulnerable component itself.
- Confidentiality
- Low — partial or indirect data access. Attacker gains limited information.
- Integrity
- Low — attacker can modify some data with limited scope or impact.
- Availability
- Low — partial or intermittent denial of service. Attacker can degrade performance.

Mitigation and Workarounds
The primary mitigation for CVE-2026-5848 is to upgrade to the patched version of JimuReport as soon as it becomes available. Since a fixed version is not yet released, immediate workarounds are limited. Consider implementing strict input validation on the dbUrl parameter within the /drag/onlDragDataSource/testConnection file to prevent malicious input. Web application firewalls (WAFs) configured to detect and block code injection attempts targeting database connection parameters could provide an additional layer of defense. Monitor JimuReport logs for suspicious activity, particularly connection attempts with unusual or malformed dbUrl values. Review and restrict network access to the JimuReport server to minimize the potential attack surface.
How to fix
Update to the patched version provided by the vendor in a future release. Verify the official jeecgboot documentation for more details on the update and any temporary mitigation measures if available. Rigorously validate and sanitize all user inputs, especially the database URL, to prevent code injection.
