[GoVulnBot]

Advisory GHSA-89p3-4642-cr2w references a vulnerability in the following Go modules:

Module
github.com/traefik/traefik
github.com/traefik/traefik/v2
github.com/traefik/traefik/v3

Description:

Impact

There is a potential vulnerability in Traefik managing STARTTLS requests.

An unauthenticated client can bypass Traefik entrypoint respondingTimeouts.readTimeout by sending the 8-byte Postgres SSLRequest (STARTTLS) prelude and then stalling, causing connections to remain open indefinitely, leading to a denial of service.
