CVE-2025-57735 is a critical vulnerability affecting Apache Airflow. When a user logs out, the JSON Web Token (JWT) they authenticated with is not invalidated, allowing for the potential reuse of that token if intercepted. This vulnerability is particularly concerning for organizations that handle sensitive data, as it can lead to unauthorized access.
The CVSS score for this vulnerability is 9.1, categorizing it as critical. The implications of such a high score indicate a significant risk to organizations, particularly those that cannot guarantee the security of their JWTs at logout.
Organizations should prioritize patching this vulnerability immediately. The recommended solution is to upgrade to Airflow version 3.2.0 or higher, where a mechanism for token invalidation upon logout has been implemented.
Failure to upgrade exposes organizations to serious risks, including potential data breaches and unauthorized access. The urgency for organizations to remediate this vulnerability cannot be overstated.
This vulnerability allows attackers to exploit the compromised session, leading to significant security incidents. With the high severity rating and the potential impact, organizations must act swiftly to mitigate the risks.
In summary, CVE-2025-57735 poses a critical threat to Apache Airflow users, and immediate action is required to secure affected systems.
Vulnerability Details
CVE-2025-57735 affects the Apache Airflow application and involves the improper handling of JWT tokens during user logout. Specifically, the lack of token invalidation allows for potential reuse of the token if intercepted. This issue was first identified in Airflow versions prior to 3.2.0, which introduced a mechanism for proper token management.
The official CVE description states that users should upgrade to version 3.2.0, which resolves this vulnerability. Understanding the implications of this vulnerability is crucial for organizations that rely on Airflow for their workflows.
The vulnerability is classified under CWE-613, which references issues related to the improper handling of security tokens. Organizations must ensure that their logout processes properly invalidate tokens to avoid these security risks.
Technical Analysis
The root cause of CVE-2025-57735 lies in the authentication flow of Apache Airflow. When a user logs out, the system fails to revoke the JWT, allowing an attacker, who may have intercepted the token, to gain unauthorized access to the application.
The attack vector is network-based, and the complexity is low. Attackers do not require any privileges or user interaction to exploit this vulnerability, making it a significant threat. The potential impacts are high in terms of confidentiality and integrity, as sensitive data may be exposed.
In terms of impacts, the vulnerability does not affect availability but poses serious risks regarding data confidentiality and integrity. Organizations must assess their exposure and implement the recommended upgrades to secure their environments.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-57735 is significant, especially for organizations that utilize Apache Airflow for managing workflows. The potential for token reuse means that compromised sessions can lead to unauthorized access, which could result in data breaches and regulatory compliance issues.
Organizations must understand the blast radius of this vulnerability. If exploited, an attacker can gain full access to user sessions and sensitive data, impacting not only the organization but also its customers and partners.
Given the critical CVSS score of 9.1, organizations should respond with urgency. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Apache Airflow prior to 3.2.0 are affected by this vulnerability. Organizations are strongly advised to upgrade to version 3.2.0 or later to ensure that JWT tokens are properly invalidated upon user logout.
Mitigation & Remediation
To mitigate the risks associated with CVE-2025-57735, organizations should upgrade to Apache Airflow version 3.2.0 or later. This version includes the necessary fixes for JWT token invalidation at logout.
In cases where immediate patching is not possible, organizations should consider implementing workarounds such as limiting the lifetime of JWT tokens or enhancing network security measures to monitor and restrict access.
Continuous security testing may also help identify any weaknesses in the token management process.
Detection Guidance
Organizations should monitor logs for any unusual authentication patterns, particularly those that indicate unauthorized access attempts using JWT tokens. It is crucial to detect any behavioral anomalies that may suggest the exploitation of this vulnerability.
Network signatures should be established to identify unauthorized token usage. Additionally, any changes in system configurations related to authentication processes should be closely tracked.
AppSecure Threat Intelligence Insight
CVE-2025-57735 highlights a critical lapse in session management practices within applications like Apache Airflow. As organizations increasingly rely on JWT for authentication, the significance of secure token handling cannot be overstated.
This vulnerability illustrates the importance of implementing robust logout mechanisms to prevent unauthorized access. Security teams should regularly audit authentication flows and ensure that proper token invalidation is enforced upon user logout.
Organizations should consider adopting best practices in session management to protect against similar vulnerabilities. For further guidance, security teams can refer to the security testing best practices and integrate them into their development processes.
As we move forward in an increasingly digital landscape, the lessons learned from vulnerabilities like CVE-2025-57735 must inform our security strategies to safeguard against future threats.
