A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service. The CVSS score of 7.5 indicates a high severity, meaning that the risk to organizations includes potential service unavailability.
This vulnerability is particularly concerning because it can be exploited without requiring any privileges or user interaction. Attackers may leverage this vulnerability to disrupt services by causing excessive resource consumption.
Given the potential impact, organizations should prioritize patching immediately. The vulnerability affects multiple configurations, including the Debian and Fedora systems.
Understanding the exploitability of this vulnerability is critical. As of now, there is no known public exploit, but the nature of the vulnerability should prompt swift action from security teams.
Vulnerability Details
The vulnerability in the minimatch package is classified under CWE-400 (Uncontrolled Resource Consumption) and CWE-1333 (Improper Handling of Length of Input). The flaw has a CVSS 3.1 vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating a network attack vector with low complexity and high availability impact.
This vulnerability affects various versions of the minimatch package and is specifically noted to impact Debian Linux 10.0 and Fedora versions 36 and 37.
The CVE was published on October 17, 2022, and its last modification was on May 13, 2025.
Technical Analysis
The root cause of the vulnerability lies in the minimatch package's braceExpand function, which can be exploited under specific conditions. The attack vector is network-based, and the complexity of the attack is low, making it accessible to a wide range of potential attackers.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impact on availability is high, as successful exploitation can lead to service outages.
Risk & Impact Analysis
Real-world deployment of the minimatch package can expose organizations to significant risk, especially if the package is used in critical applications. The potential for service disruption necessitates immediate attention from security teams.
With the CVSS score of 7.5, this vulnerability falls into the high severity category, indicating that organizations should address it in their priority patch cycle.
The blast radius is potentially extensive, as many systems rely on the minimatch package for various functionalities. Organizations that fail to address this vulnerability may face service interruptions and increased operational costs.
