Nginx Gateway Fabric
Monthly
Configuration injection in NGINX Gateway Fabric allows authenticated Kubernetes users with CRD or Secret write permissions to embed arbitrary NGINX directives into the generated server configuration. The vulnerability originates in the NGINX configuration generator component, which renders Authentication Filter fields - clientID, cookieName, and clientSecret - directly into configuration templates without sanitization. Successful exploitation is limited to the control plane; no data-plane traffic is directly manipulated, but an attacker can introduce directives that compromise confidentiality and integrity of the NGINX Plus configuration. No public exploit has been identified and the issue is not listed in CISA KEV at time of analysis.
Denial-of-service in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with rights to create or modify GRPCRoute resources to crash the control plane by submitting GRPCRoute objects containing malformed backendRef filters. The flaw, tracked under CWE-129 (Improper Validation of Array Index), carries a CVSS 4.0 score of 7.1 with pure availability impact and no public exploit identified at time of analysis.
Configuration injection in F5 NGINX Gateway Fabric allows an authenticated Kubernetes user with permission to create or modify NginxProxy Custom Resource Definitions to inject arbitrary NGINX directives into generated configuration files via the unsanitized access log format setting. The flaw resides in the control plane configuration generator and affects deployments using NGINX Plus or NGINX Open Source as the data plane. There is no public exploit identified at time of analysis, and CVSS 4.0 rates the impact at 8.6 (High) driven by high confidentiality and integrity loss on the vulnerable system.
Configuration injection in F5 NGINX Gateway Fabric lets an authenticated Kubernetes user who can create or modify NginxProxy or AuthenticationFilter Custom Resources inject arbitrary NGINX directives into generated data-plane configuration. The flaw lives in the control-plane config generator, which renders the serverTokens and extraAuthArgs fields into NGINX templates without escaping, so any tenant holding RBAC rights over these CRDs can rewrite the NGINX Plus config that gets deployed. There is no public exploit identified at time of analysis and EPSS is low (0.36%), but SSVC rates the technical impact as total.
NGINX proxy configurations forwarding traffic to upstream TLS servers can be exploited by network-positioned attackers to inject unencrypted data into proxied responses, potentially compromising data integrity. This vulnerability affects NGINX OSS, NGINX Plus, and related products when specific upstream server conditions are present. No patch is currently available for this medium-severity issue.
