Traefik v2.11.62 releases bug fixes for authentication and path parameter resolution

Traefik has released version 2.11.62 of its cloud-native edge router. This update focuses on addressing specific bugs within the authentication subsystem and the server's path resolution logic.

Users managing edge routing and proxy services will benefit from enhanced security constraints on BasicAuth and improved handling of complex URL segments. The release also includes a dependency update for the Yaegi interpreter used in the plugin system.

Technical improvements in Traefik v2.11.62

• Authentication Security: Implements a length limit on BasicAuth passwords to prevent potential issues with excessively long credentials.
• Proxy Protocol Support: Adds support for connection-bound authentication schemes within the Proxy-Authorization header.
• Path Parameter Logic: Resolves issues related to dot-segments and empty segments when utilizing path parameters in the server component.
• Plugin Dependency: Updates the internal yaegi interpreter to version 0.16.3 to maintain plugin compatibility and stability.

Why it matters

This release provides critical stability and security hardening for DevOps engineers and system administrators using Traefik as a reverse proxy. The fixes to path parameter resolution ensure more predictable routing behavior in complex microservices architectures.
