The vulnerability identified as CVE-2025-0937 affects both Nomad Community and Nomad Enterprise. This vulnerability allows event streams configured with a wildcard namespace to bypass the ACL Policy, enabling unauthorized reads on other namespaces. As a result, the confidentiality of sensitive data may be compromised, making it crucial for organizations utilizing Nomad to address this issue promptly.
With a CVSS score of 7.1, this vulnerability is classified as high severity. The attack vector is network-based, and the attack complexity is low, meaning that attackers may exploit this vulnerability relatively easily. Given the potential impact on data confidentiality, organizations must take immediate action to remediate this flaw.
Currently, there is no known public exploit for this vulnerability, and it has not been classified as actively exploited in the wild. However, the risk to organizations includes unauthorized access to sensitive information, which highlights the urgency of applying patches to affected systems.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. Regular monitoring and security assessments should also be conducted to ensure compliance and to detect any potential exploitation attempts.
Vulnerability Details
CVE-2025-0937 allows event streams in Nomad to bypass ACL policies when configured with a wildcard namespace. This could lead to unauthorized access to data across different namespaces. The vulnerability has been assigned a CVSS score of 7.1, indicating a high severity level. The vulnerability was disclosed on February 12, 2025, and is categorized under CWE-863, which relates to improper authorization.
Technical Analysis
The root cause of this vulnerability is related to the misconfiguration of ACL policies in Nomad. When wildcard namespaces are utilized, it allows for a bypass of the intended restrictions, leading to potential unauthorized access to sensitive data. The attack vector is network-based, and the complexity of the attack is low, with low privileges required for exploitation. User interaction is not necessary, which increases the risk associated with this vulnerability. The impact on confidentiality is high, while the integrity impact is low and there is no availability impact.
Risk & Impact Analysis
The deployment of Nomad in sensitive environments can expose organizations to significant risks due to this vulnerability. The ability for unauthorized users to access data across namespaces can lead to data breaches and loss of sensitive information. The potential blast radius is considerable, especially in organizations where Nomad is integrated with other critical systems. Organizations must assess the urgency based on the CVSS score and implement patches as part of their priority patch cycle.
