Advisory Summary

CVE-2026-86740 is a MODERATE (CVSS 3.8) security vulnerability vulnerability (CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-86740

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-2026-86740, 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-212: Improper Removal of Sensitive Information Before Storage or Transfer, where the product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors. 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

Snipe-IT before 8.7.0 fails to check the return value of Storage::delete() in UploadedFilesController::destroy() and Api\\UploadedFilesController::destroy(), allowing deletion requests to report success while files remain on disk. Administrators performing attachment deletions receive success responses and see files hidden from listings, but the physical files persist on disk and remain accessible to anyone with filesystem or backup access.
