    CVE-2026-66362 (GCVE-0-2026-66362)

    Title
    NGF vulnerability
    Summary
    Description: When NGINX Plus is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the Authentication Filter Custom Resource Definition clientID or cookieName fields, or in the clientSecret field of a Secret referenced by an Authentication Filter, are rendered directly into NGINX configuration templates without sanitization or escaping. Impact: An authenticated attacker with permission to create or modify these resources may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure.

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Plus or NGINX Open Source is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the NginxProxy Custom Resource Definition (CRD) access log format setting are rendered directly into NGINX configuration templates without sanitization or escaping. An authenticated attacker with permission to create or modify these CRDs may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure from the vulnerability trigger itself. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Gateway Fabric is configured using GRPCRoutes, an authenticated, remote attacker with permission to create or modify GRPCRoute resources can cause the NGINX Gateway Fabric control plane to terminate by sending undisclosed GRPCRoute configurations containing backendRef filters. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Plus is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the NginxProxy Custom Resource Definition serverTokens field and the AuthenticationFilter Custom Resource Definition extraAuthArgs field are rendered directly into NGINX configuration templates without sanitization or escaping. An authenticated attacker with permission to create or modify these Custom Resource Definitions may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure from the vulnerability trigger itself. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

    Title
    NGF vulnerability
    Summary
    Description: When NGINX Plus is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the Authentication Filter Custom Resource Definition clientID or cookieName fields, or in the clientSecret field of a Secret referenced by an Authentication Filter, are rendered directly into NGINX configuration templates without sanitization or escaping. Impact: An authenticated attacker with permission to create or modify these resources may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure.

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Gateway Fabric is configured using GRPCRoutes, an authenticated, remote attacker with permission to create or modify GRPCRoute resources can cause the NGINX Gateway Fabric control plane to terminate by sending undisclosed GRPCRoute configurations containing backendRef filters. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Plus or NGINX Open Source is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the NginxProxy Custom Resource Definition (CRD) access log format setting are rendered directly into NGINX configuration templates without sanitization or escaping. An authenticated attacker with permission to create or modify these CRDs may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure from the vulnerability trigger itself. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

    CVE-2026-11311 (GCVE-0-2026-11311)

    Vulnerability from cvelistv5 – Published: 2026-06-17 14:04 – Updated: 2026-06-17 15:42 X_F5

    Title
    NGINX Gateway Fabric vulnerability
    Summary
    When NGINX Plus is configured as the data plane for NGINX Gateway Fabric, an injection vulnerability exists in the NGINX configuration generator component of NGINX Gateway Fabric. User-supplied string values from the NginxProxy Custom Resource Definition serverTokens field and the AuthenticationFilter Custom Resource Definition extraAuthArgs field are rendered directly into NGINX configuration templates without sanitization or escaping. An authenticated attacker with permission to create or modify these Custom Resource Definitions may craft values that inject arbitrary NGINX configuration directives. This is a control plane issue; there is no data plane exposure from the vulnerability trigger itself. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
