CVE-2026-40552: Software Security Vulnerability Vulnerability
MODERATECVE-2026-40552 is a MODERATE security vulnerability vulnerability (CWE-669: Incorrect Resource Transfer Between Spheres) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-40552 at a Glance
How to Fix CVE-2026-40552
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-40552, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree
Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-669: Incorrect Resource Transfer Between Spheres, where the product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource.

"details" : "mpGabinet is vulnerable to Remote Command Execution. An authorized user with access to the application and direct access to the backend database can achieve system command execution by uploading an attachment and modifying its storage path in the database to reference an attacker-controlled remote network resource. Alternatively, it is possible to use a previously uploaded file and change its reference. When the application processes the attachment, and a user tries to open it, the referenced resource is executed by the system.\nCritically, this vulnerability can be exploited by any unauthenticated attacker by chaining it with CVE-2026-40550 and CVE-2026-40551, which allows obtaining database access, and logging onto any account.\n\nThis issue affects mpGabinet version 23.12.19 and below.",
