CVE-2026-11457: JeeWMS JimuReport Injection Vulnerability – Exploitation & Remediation Guide

Technical summary

CVE-2026-11457 is an injection vulnerability affecting erzhongxmu JeeWMS up to commit 141740afb2ba14d441c82a833d0a418d07ca2d69. The vulnerability resides in the /base-boot/jmreport/testConnection endpoint of the JimuReport component. The endpoint fails to properly validate or sanitize user-supplied input in the dbType, dbDriver, dbUrl, dbUsername, and dbPassword parameters. This inadequate input handling permits argument injection, allowing remote unauthenticated attackers to execute arbitrary payloads. The CVSS v3.1 score of 7.3 (HIGH) reflects the network-accessible nature of the endpoint, lack of authentication requirement, and impact across confidentiality, integrity, and availability.

Business impact

For organizations deploying JeeWMS, this vulnerability poses a direct threat to database security and warehouse operations continuity. An attacker could extract sensitive data from connected databases, modify critical inventory records, or disable warehouse systems entirely. The existence of public exploit code dramatically shortens the window between vulnerability disclosure and potential exploitation, particularly affecting businesses that rely on JeeWMS for supply chain visibility or order fulfillment. Unpatched instances are exposed to both opportunistic and targeted attacks.

Affected systems

JeeWMS installations up to commit 141740afb2ba14d441c82a833d0a418d07ca2d69 are vulnerable. The project uses a rolling release model without discrete version numbering, making it difficult to identify affected releases through traditional version comparison. Organizations should verify their deployed commit hash against the disclosed commit to determine exposure. Any instance exposing the /base-boot/jmreport/testConnection endpoint to network access is at risk.

Exploitability

This vulnerability is readily exploitable. No authentication is required to access the endpoint, and the attack surface is straightforward: manipulation of five database connection parameters. Network-level access is sufficient; the endpoint does not require user interaction or special privileges. The release of public exploit code confirms proof-of-concept availability, significantly increasing the likelihood of active exploitation in the wild. Attack complexity is low, and the vulnerability can be triggered with simple HTTP requests, making it accessible to attackers with basic technical skills.

Remediation

Apply the latest version of JeeWMS after the disclosed vulnerable commit. Because the project uses continuous delivery, consult the official JeeWMS repository for the most recent commit that addresses this injection flaw. Additionally, implement network-level controls to restrict access to the /base-boot/jmreport/testConnection endpoint to trusted hosts only. If immediate patching is not possible, disable the JimuReport test-connection functionality or remove the endpoint entirely if not critical to operations.

Patch guidance

Monitor the erzhongxmu JeeWMS repository for commits that remediate this injection vulnerability post-2026-06-07. Since the vendor did not respond to early disclosure attempts, patches may come through community contributions or updates without formal vendor communication. Verify any applied patches by: (1) confirming the deployed commit is after 141740afb2ba14d441c82a833d0a418d07ca2d69, (2) reviewing code changes to the /base-boot/jmreport/testConnection endpoint to ensure input validation is in place, and (3) testing that malformed dbType, dbDriver, dbUrl, dbUsername, and dbPassword parameters are properly rejected or escaped.

Detection guidance

Monitor for HTTP requests to /base-boot/jmreport/testConnection that contain unusual or suspicious database parameter values. Specifically, look for payloads in dbType, dbDriver, dbUrl, dbUsername, or dbPassword fields that contain special characters, SQL keywords, or command-line syntax (e.g., semicolons, pipes, backticks). Web application firewalls should be configured to detect and block requests with parameter manipulation attempts. Network intrusion detection systems should alert on database connection attempts originating from the application server to unexpected hosts or ports, which may indicate successful exploitation.

Why prioritize this

HIGH priority remediation is warranted due to the combination of network accessibility, lack of authentication requirements, public exploit availability, and direct impact on data confidentiality and system availability. The rolling release model creates additional complexity in tracking affected instances, increasing the risk of inadvertent exposure. Organizations managing critical warehouse or supply chain operations should treat this as urgent.

Risk score, explained

The CVSS v3.1 score of 7.3 (HIGH) reflects an attack vector that is network-based (AV:N), requires no special conditions to exploit (AC:L), does not require authentication (PR:N), needs no user interaction (UI:N), and affects only the vulnerable component without scope expansion (S:U). The impact across confidentiality, integrity, and availability (each rated Low) aggregates to a HIGH severity rating. The presence of public exploit code and lack of vendor response further elevate practical risk beyond the base CVSS assessment.
