Traefik is an open source HTTP reverse proxy and load balancer. In affected versions there is a potential vulnerability in Traefik managing TLS connections. A router configured with a not well-formatted TLSOption is exposed with an empty TLSOption. For instance, a route secured using an mTLS connection set with a wrong CA file is exposed without verifying the client certificates. Users are advised to upgrade to version 2.9.6. Users unable to upgrade should check their logs to detect the error messages and fix your TLS options.

GHSA-468w-8x39-gj5v — Traefik routes exposed with an empty TLSOption

2026-10-04T17:56:43.359153+00:00

Affected: Go: github.com/traefik/traefik/v2

## Impact

There is a potential vulnerability in Traefik managing the TLS connections.

A router configured with a not well-formatted [TLSOption](https://doc.traefik.io/traefik/v2.9/https/tls/#tls-options) is exposed with an empty TLSOption.

For instance, a route secured using an mTLS connection set with a wrong CA file is exposed without verifying the client certificates.

## Patches

https://github.com/traefik/traefik/releases/tag/v2.9.6

## Workarounds

Check the logs to detect the following error messages and fix your TLS options:

- Empty CA:

``` {"level":"error","msg":"invalid clientAuthType: RequireAndVerifyClientCert, CAFiles is required","routerName":"Router0@file"} ```

- Bad CA content (or bad path):

``` {"level":"error","msg":"invalid certificate(s) content","routerName":"Router0@file"} ```

- Unknown Client Auth Type:

``` {"level":"error","msg":"unknown client auth type \"FooClientAuthType\"","routerName":"Router0@file"} ```

- Invalid cipherSuites

``` {"level":"error","msg":"invalid CipherSuite: foobar","routerName":"Router0@file"} ```

- Invalid curvePreferences

``` {"level":"error","msg":"invalid CurveID in curvePreferences: foobar","routerName":"Router0@file"} ```
