CVE-2026-7603
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceServer-Side Request Forgery (SSRF) vulnerability in JeecgBoot up to v3.9.1 in the LoadFile endpoint's checkPathTraversalBatch function within FileDownloadUtils.java. The function fails to properly validate URL/path inputs, allowing remote attackers to induce the server to make arbitrary requests to internal or external resources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm JeecgBoot is deployedIdentify if your application is running JeecgBoot by checking the application name, framework artifacts, or startup logs. Look for JeecgBoot-specific indicators in your deployment.Affected if The application is confirmed to be JeecgBoot
-
Determine the installed JeecgBoot versionCheck the version information from your deployment artifacts, pom.xml, build configuration, or application metadata. Compare your version against the affected range: all versions up to and including v3.9.1 are vulnerable.Affected if The installed version is v3.9.1 or any earlier version
-
Verify the LoadFile endpoint is exposedDetermine if the LoadFile endpoint is accessible in your environment by reviewing your routing configuration, API documentation, or network exposure settings. This endpoint is located in FileDownloadUtils.java.Affected if The LoadFile endpoint is accessible from your network
-
Inspect the checkPathTraversalBatch functionLocate FileDownloadUtils.java in your codebase and examine the checkPathTraversalBatch function. Verify whether it performs proper validation on URL and path inputs before processing requests.Affected if The function lacks proper input validation on URL/path parameters
You are affected if you are running JeecgBoot version 3.9.1 or earlier with the LoadFile endpoint accessible and the checkPathTraversalBatch function missing proper input validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch when released; until then, restrict network access to the LoadFile endpoint and implement additional input validation/allowlist controls on the checkPathTraversalBatch function.
