Advisory Summary

CVE-2026-56652 is a MODERATE security vulnerability vulnerability (CWE-1236: Improper Neutralization of Formula Elements in a CSV File) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product saves user-provided information into a comma-separated value (csv) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-56652

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-2026-56652, 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-1236: Improper Neutralization of Formula Elements in a CSV File, where the product saves user-provided information into a comma-separated value (csv) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product. 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

Dool in versions up to 1.3.8 is vulnerable to a CSV injection vulnerability when exporting data to a CSV file, as it fails to sanitize cell content beginning with special formula characters like =, +, -, or @. A local attacker can exploit this by running a process with a crafted name starting with =, which injects malicious formulas into the CSV output that execute when a victim opens the file in a spreadsheet application.  The issue was addressed by pull request #117
