How to Fix CVE-2026-112157

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.

Verify Direct and Transitive Dependencies

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-2026-112157, 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A weakness has been identified in MemTensor memmy-agent up to 1.0.9/1.1.1/1.2.2. The impacted element is the function requireAdminWrite of the file Memory/src/server/http.ts of the component Memory Service. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The exploit is partially overstated. While "POST /api/v1/admin/shutdown" accepts unauthenticated requests when no token is configured, it’s designed for local use and later received cross-origin fixes. Unauthenticated endpoint exposure is confirmed; browser-triggered DoS remains likely but depends on specific browser behavior.
