How to Fix CVE-2026-80432

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-2026-80432, 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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

Missing Authorization in the drop handling path of the drag and drop protocol in kitty from 0.47.0 before 0.49.0 allows a program writing to the terminal to obtain the contents of files dragged over the window even when the user never completes the drop, because drop_enqueue_request() in kitty/dnd.c serves a drag data request without first checking the drop state of the window, so a client that issues the request while a drag is merely hovering receives the data offered for the drag. In the same file, drop_left_child(), which runs when the drag leaves the window without a drop having occurred, releases the offered MIME list but retains the pending request state, the open file descriptor and its main loop transfer timer, the directory handles, the URI list and the pending MIME name, so a client can continue to read through a retained directory handle, and an in-flight file transfer continues to stream, when no drag is in progress. The file contents are read from the filesystem by the kitty process itself using the paths the drag source offered. This results in disclosure of the contents of files the user moved over the window without ever releasing them into it.
