CVE-2025-24514 is a high-severity vulnerability that affects the Ingress-NGINX controller, specifically concerning the `auth-url` annotation. This security issue can lead to arbitrary code execution in the context of the ingress-nginx controller and the disclosure of Secrets accessible to the controller. Notably, in a default installation, the controller has access to all Secrets cluster-wide, significantly increasing the potential impact of this vulnerability.
The CVSS score of 8.8 categorizes this vulnerability as high severity, indicating a critical need for immediate attention from organizations leveraging Ingress-NGINX. The attack vector is network-based, which means attackers could exploit this vulnerability remotely with relatively low complexity. Given the potential for arbitrary code execution, organizations should treat this vulnerability with urgency.
Current exploit availability is high, with confirmed public exploits documented. Security teams must act swiftly to mitigate risks associated with this vulnerability, particularly as it can lead to unauthorized access and exposure of sensitive information.
Organizations should prioritize patching immediately to protect against potential exploitation of CVE-2025-24514, ensuring their deployment remains secure.
Vulnerability Details
The vulnerability is identified as a configuration injection issue due to the unsanitized `auth-url` annotation in Ingress-NGINX. The official description states: 'A security issue was discovered in ingress-nginx where the `auth-url` Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller.'
The vulnerability is classified under CWE-20, which refers to improper input validation. The CVSS score of 8.8 indicates significant risk, with the following metrics: an attack vector of NETWORK, low attack complexity, low privileges required, and high impacts on confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2025-24514 stems from insufficient validation of the `auth-url` annotation in Ingress-NGINX. This allows attackers to inject malicious configurations into the nginx controller, potentially executing arbitrary code. The attack vector is network-based, meaning that an attacker does not require physical access to the network to exploit this vulnerability.
The attack complexity is rated as low, as it does not require advanced skills to exploit. Attackers need to have low privileges, and no user interaction is required to trigger the exploit. The implications of a successful attack could lead to high impacts on confidentiality, integrity, and availability, making this a severe threat.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive information and potential system compromise. The vulnerability's ability to manipulate the ingress-nginx controller means that an attacker could gain control over the entire cluster's configurations, leading to severe operational impacts.
With a CVSS score of 8.8, organizations should address this vulnerability in their priority patch cycle. The urgency is underscored by the high availability of exploits and the potential for significant damage from successful attacks.

Affected Versions
All versions of ingress-nginx prior to the release of a patch addressing this vulnerability are likely affected. Organizations should check for updates from the official Ingress-NGINX repository.
Mitigation & Remediation
Organizations should prioritize patching to the latest version of ingress-nginx that addresses the `auth-url` annotation vulnerability. If an immediate patch is not available, consider implementing configuration hardening measures to limit the exposure of sensitive configurations and Secrets.
Continuous monitoring and security testing are recommended to identify potential misconfigurations and vulnerabilities within the ingress-nginx deployments. For further guidance, organizations can refer to our penetration testing services for a comprehensive security assessment.
Detection Guidance
To detect potential exploitation of CVE-2025-24514, organizations should monitor logs for unusual configurations being applied via `auth-url` annotations. Look for behavioral anomalies in ingress-nginx traffic patterns that may indicate attempts to exploit this vulnerability.
Additionally, keep an eye on any unauthorized access attempts to Secrets that the ingress-nginx controller has access to, as this could indicate a successful breach.
