A vulnerability was determined in JeecgBoot up to 3.9.1. Affected by this issue is the function checkPathTraversalBatch of the file FileDownloadUtils.jav of the component LoadFile Endpoint. This manipulation of the argument files causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The affected component should be upgraded. The vendor confirmed the issue and will provide a fix in the upcoming release.
The severity level of this vulnerability is classified as low with a CVSS score of 2.1. Although the score indicates a lower risk, the potential for server-side request forgery should not be underestimated. Organizations using JeecgBoot should evaluate their exposure and consider necessary mitigations.
Risk to organizations includes potential unauthorized access to internal systems through SSRF attacks, which can lead to data exposure and further exploitation. Organizations should prioritize patching immediately to secure their applications.
As of now, there is no public exploit confirmed, but the vulnerability is known, and organizations should remain vigilant. Immediate action is recommended to mitigate any potential risks.
Vulnerability Details
The vulnerability allows for server-side request forgery (SSRF) in JeecgBoot up to version 3.9.1. The CVSS score is 2.1, indicating a low severity level. The affected component is the LoadFile Endpoint, specifically the checkPathTraversalBatch function in FileDownloadUtils.jav. The vulnerability was published on May 2, 2026.
The Common Weakness Enumeration (CWE) classification for this vulnerability is CWE-918. Organizations should take note of this vulnerability and plan for remediation.
Technical Analysis
Root cause analysis indicates that the vulnerability arises from improper handling of file arguments in the LoadFile Endpoint. Attackers may leverage this vulnerability to perform SSRF attacks, potentially leading to unauthorized access to internal services.
The attack vector is network-based, with low complexity and low privileges required. User interaction is not necessary, making this vulnerability particularly concerning.
Risk & Impact Analysis
Real-world deployment risk includes unauthorized access to internal systems, which could lead to data breaches or the compromise of further resources. Organizations should assess their risk exposure and prioritize vulnerability management accordingly.
The potential blast radius includes any internal services accessible from the server running JeecgBoot. Organizations should ensure that network segmentation and internal access controls are in place to mitigate this risk.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of JeecgBoot prior to 3.9.1 are affected by this vulnerability. Organizations should upgrade to the latest version as soon as it is available from the vendor.
Mitigation & Remediation
Organizations should patch and upgrade to the latest version of JeecgBoot as soon as it becomes available. If immediate patching is not possible, consider implementing workarounds such as restricting access to the LoadFile Endpoint and validating file inputs to prevent SSRF.
For further guidance, organizations can refer to resources on penetration testing to assess their security posture.
Detection Guidance
Organizations should monitor logs for any unusual access patterns to the LoadFile Endpoint and validate file inputs. Implementing network segmentation can also help mitigate risks associated with SSRF.
