CVE-2025-1097

A security issue was discovered in [ingress-nginx](https://github.com/kubernetes/ingress-nginx) where the auth-tls-match-cn 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. (Note that in the default installation, the controller can access all Secrets cluster-wide.)

A Nuclei detection template exists for this, which means it is scanned for at internet scale rather than looked for deliberately.

Signals come from Exploit-DB, Metasploit, Nuclei and published proof-of-concept repositories. Their absence means nothing was found, not that nothing exists.
