CVE-2025-1293 is a high-severity vulnerability discovered in HashiCorp's Hermes, specifically affecting versions up to 0.4.0. This vulnerability allows for improper validation of JSON Web Tokens (JWTs) when utilizing the AWS Application Load Balancer (ALB) authentication mode, which could lead to authentication bypass. The flaw was addressed in Hermes version 0.5.0, and organizations utilizing this software should prioritize updating to the latest version to mitigate potential risks.
The CVSS score for this vulnerability is 8.2, indicating a high severity level. The risk to organizations includes potential unauthorized access, which could lead to further exploitation within the network. Given the nature of this vulnerability, it is crucial for security practitioners to understand its implications and act swiftly to implement the necessary patches.
Currently, there are no known exploits for CVE-2025-1293, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. Nevertheless, the nature of the vulnerability necessitates vigilance as attackers may leverage similar issues to gain unauthorized access. Organizations should prioritize patching immediately to secure their systems.
To summarize, CVE-2025-1293 poses a significant risk to users of HashiCorp Hermes, and immediate remediation efforts are essential to safeguard against potential threats. Security teams are advised to stay updated on this and other vulnerabilities to maintain a robust security posture.
Vulnerability Details
The official description of CVE-2025-1293 states that Hermes versions up to 0.4.0 improperly validate the JWT provided when using the AWS ALB authentication mode, potentially allowing for authentication bypass. This vulnerability was fixed in Hermes 0.5.0.
The vulnerability type is classified under CWE-1390. The CVSS score is 8.2, indicating a high severity level. The attack vector is adjacent network, with low attack complexity and no privileges required for exploitation, making it easier for attackers to exploit this flaw.
The vulnerability affects the HashiCorp Hermes product, specifically all versions prior to the vendor patch (0.5.0).
Technical Analysis
The root cause of CVE-2025-1293 lies in the improper validation of JWTs within the AWS ALB authentication mode. This flaw can be exploited through adjacent network access, allowing attackers to bypass authentication without needing any privileges or user interaction. The impact of this vulnerability on confidentiality is high, while the integrity impact is low, and availability remains unaffected.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-1293 is significant, as it could allow unauthorized access to systems that rely on AWS ALB for authentication. This vulnerability not only poses a direct threat to the affected system but could also have a broader blast radius if exploited to gain access to sensitive data or system functionalities.
Organizations should assess their environments for the presence of vulnerable versions of Hermes and prioritize patching as part of their vulnerability management program. The urgency for remediation is high due to the potential for exploitation.

Affected Versions
All versions of HashiCorp Hermes prior to 0.5.0 are affected by this vulnerability. Organizations using these versions should upgrade to 0.5.0 or later to mitigate risks.
Mitigation & Remediation
To remediate CVE-2025-1293, organizations should upgrade to HashiCorp Hermes version 0.5.0 or later. In cases where immediate upgrading is not possible, implementing additional authentication mechanisms or controls could provide interim protection. Configuration hardening should also be considered to restrict access to vulnerable components.
For ongoing protection, organizations can benefit from engaging in continuous penetration testing to identify and address similar vulnerabilities before they can be exploited.
Detection Guidance
Organizations should monitor system logs for indicators of unauthorized access attempts related to JWT authentication failures. Additionally, behavioral anomalies in user access patterns and network signatures that correspond to typical exploitation attempts should be observed.
AppSecure Threat Intelligence Insight
CVE-2025-1293 exemplifies a significant vulnerability pattern that organizations must be aware of, particularly regarding authentication mechanisms. As organizations increasingly adopt cloud-based services and components like AWS ALB, the validation of JWTs becomes crucial in preventing unauthorized access.
This vulnerability serves as a reminder for security teams to conduct regular security assessments and engage in vulnerability management programs to identify and mitigate risks effectively before they can be exploited.
Furthermore, adopting a proactive approach through penetration testing methodologies can help organizations stay ahead of emerging threats and vulnerabilities, ensuring robust security.
