Advisory Summary

CVE-2026-72847 is a LOW (CVSS 4.6) security vulnerability vulnerability (CWE-150: Improper Neutralization of Escape, Meta, or Control Sequences) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-72847

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-2026-72847, 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-150: Improper Neutralization of Escape, Meta, or Control Sequences, where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component. 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

broot renders each file and directory name in its interactive tree view exactly as read from the filesystem. Names are converted with a plain to_string_lossy() call in src/tree_build/builder.rs and in TreeLine::unprune in src/tree/tree_line.rs, and no control-character filtering exists anywhere in the code, even though the doc comment on the TreeLine name field states that some characters may have been stripped. Any local user who can create a file can therefore place an escape sequence in its name and have it written unmodified to the terminal of anyone who browses that directory, between broot's own styling codes. A reported proof of concept used an OSC 52 clipboard-write sequence and captured the raw bytes broot wrote to its pty, confirming the sequence reaches the terminal unstripped. What an injected OSC or CSI sequence can then do depends on the terminal emulator in use. Browsing a directory is broot's primary function and carries no expectation that the content is trusted.
