Vulnerability from github – Published: 2026-10-14 15:32 – Updated: 2026-10-14 15:32

Details

Description NGINX Gateway Fabric has a vulnerability when it is configured with Gateway

Custom Resource Definition (CRD) and have an authenticated gRPC connection with NGINX Agent. A namespaced

authenticated attacker with access to a service account may impersonate the authenticated NGINX Agent gRPC connection to read TLS private keys of Gateway deployments in another namespace.

Impact A remote authenticated attacker may be able to read TLS private keys of Gateway deployments in another namespace.

There is no data plane exposure; this is a control plane issue only.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
