CVE-2025-22235 represents a high-severity vulnerability classified under CVSS 3.1 with a score of 7.3. This vulnerability allows unauthorized access to protected paths in applications using Spring Security if specific conditions are met. It is imperative for organizations utilizing this framework to understand the implications and take necessary actions.
The vulnerability arises when the EndpointRequest.to() creates a matcher for null/** if the actuator endpoint is disabled or not exposed. This can lead to serious security risks, as attackers may exploit this misconfiguration to access sensitive application endpoints.
Risk to organizations includes unauthorized access to protected resources. Given the exploitability of this vulnerability is rated high, organizations must prioritize addressing this issue in their security patch cycles.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. If your application meets the outlined conditions, immediate remediation is necessary.
Vulnerability Details
The CVE-2025-22235 vulnerability description indicates that applications may be affected if they use Spring Security, utilize EndpointRequest.to() in their configuration, and handle requests to /null that require protection. The official CVE description emphasizes that systems not meeting these criteria are not impacted.
The CVSS score of 7.3 categorizes this vulnerability as high severity, highlighting its potential impact. This classification stems from factors such as low attack complexity and the requirement for no privileges or user interaction, making it accessible for exploitation.
The vulnerability was published on April 28, 2025, and is classified under CWE-20, indicating improper input validation. Prompt action is essential for affected organizations to maintain security integrity.
Technical Analysis
The root cause of CVE-2025-22235 lies in how Spring Security processes endpoint requests. When the EndpointRequest.to() method is called, it generates a matcher for null/** if the respective actuator endpoint is either disabled or not exposed. This creates unintended security loopholes for applications.
The attack vector for this vulnerability is classified as network-based, allowing attackers to exploit it remotely without physical access to the system. Given the low complexity of the attack, even less experienced attackers can potentially trigger the vulnerability.
No privileges are required for exploitation, and user interaction is not necessary, which increases the likelihood of successful attacks. The confidentiality, integrity, and availability impacts are all rated as low, but the potential for unauthorized access remains a serious concern.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22235 is significant, particularly for organizations that rely heavily on Spring Security for protecting their applications. Failure to address this vulnerability could lead to unauthorized access to sensitive data or functionalities.
This vulnerability can have a wide blast radius, especially in environments where multiple applications or services are interconnected. The urgency for remediation is underscored by its high CVSS score and the confirmed existence of exploit availability.
Given the high exploitability, organizations should address this vulnerability in their priority patch cycle. The longer it remains unpatched, the greater the risk of an attacker leveraging this vulnerability for unauthorized access.

Affected Versions
Specific version ranges affected by this vulnerability are not detailed. Organizations should consider all versions of Spring Security that utilize EndpointRequest.to() and potentially handle requests to /null without proper endpoint exposure as vulnerable.
Mitigation & Remediation
Organizations should prioritize patching to the latest version of Spring Security that addresses CVE-2025-22235. Implementing appropriate security configurations to expose necessary actuator endpoints while properly securing others is critical.
In cases where immediate patching is not feasible, consider implementing network controls to restrict access to sensitive endpoints and monitor for any unauthorized access attempts.
For further guidance, organizations can refer to the complete application security checklist available at AppSecure which provides a comprehensive overview of best practices.
Detection Guidance
Monitoring logs for indicators of unauthorized access attempts to the /null endpoint is essential. Detecting behavioral anomalies in the handling of requests can also help identify potential exploitation of this vulnerability.
Additionally, implementing network signatures that track unusual traffic patterns aimed at unsecured endpoints can enhance detection capabilities.
AppSecure Threat Intelligence Insight
CVE-2025-22235 reflects a growing trend in vulnerabilities associated with misconfiguration. Security teams should continuously evaluate their configurations to prevent similar vulnerabilities.
This case highlights the critical importance of properly managing actuator endpoints to ensure that sensitive paths are secured effectively. Organizations can benefit from conducting regular security assessments, such as penetration testing, to identify and remediate configuration weaknesses.
Security teams should also consider integrating best practices for secure coding and implementation of application security frameworks into their development processes. For example, engaging in secure coding practices can help prevent vulnerabilities like CVE-2025-22235 in the future.
Overall, the strategic takeaway from this vulnerability is the necessity for vigilance in security configurations and the proactive management of application security.
