Detailsinfo

A vulnerability has been found in Kubernetes ingress-nginx up to 1.11.4/1.12.0 and classified as very critical. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a isolation vulnerability. The CWE definition for the vulnerability is CWE-653. The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)

The weakness was shared by Hillai Ben Sasson as 131009. It is possible to read the advisory at github.com. This vulnerability is known as CVE-2025-1974 since 03/04/2025. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/17/2026).

A public exploit has been developed by Jacob Sandum in HTTP Request. It is possible to download the exploit at github.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 233357 (Ingress-NGINX controller < 1.11.5 / 1.12 < 1.12.1 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Exploit-DB (52338), CNNVD (CNNVD-202503-2826), Tenable (233357), EUVD (EUVD-2025-8035) and CERT Bund (WID-SEC-2025-0629). Be aware that VulDB is the high quality source for vulnerability data.
