Advisory Summary

CVE-2026-87678 is a MODERATE (CVSS 5.2) security vulnerability vulnerability (CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs.. Remediation is available in the latest vendor maintenance releases.

Integrity Low (I:L)
Availability High (A:H)

How to Fix CVE-2026-87678

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-2026-87678, 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-93: Improper Neutralization of CRLF Sequences ('CRLF Injection'), where the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs. 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

An input validation and output encoding vulnerability exists in the web management interface of Brocade Fabric OS versions before 10.0.1. When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator—or an attacker capable of supplying crafted FA configuration files during an import routine—can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.
