# CVE-2025-24513: ingress-nginx controller - auth secret file path traversal vulnerability

**Signal:** Normal patch cycle. No exploitation signal; fix it in your next routine update if you are affected. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 3.3% , percentile 89: FIRST’s model estimates a 3.3% chance of exploitation activity in the next 30 days, higher than 89% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Check exposure. IngressNightmare: ingress-nginx Cluster Takeover RCE — Patched since March 2025. If any cluster still runs ingress-nginx below 1.11.5 or 1.12.1, that is a cluster-takeover risk, and the controller itself is now retired, so plan the migration while you check.

## What it is

A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where attacker-provided data are included in a filename by the ingress-nginx Admission Controller feature, resulting in directory traversal within the container. This could result in denial of service, or when combined with other vulnerabilities, limited disclosure of Secret objects from the cluster.

## Affected products (CVE record)

- kubernetes ingress-nginx: <= 1.11.4, 1.12.0

## Severity

- kubernetes CVSS 3.1: 4.8 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 3.33% probability of exploitation activity in the next 30 days; percentile 89.
