CVE-2025-68156 Remediation + +**Date:** January 11, 2026 +**Priority:** CRITICAL +**Estimated Time:** 3-4 hours +**Target Completion:** Within 48 hours + +--- + +## Executive Summary + +This plan details the implementation to build CrowdSec from source in the Dockerfile to remediate **CVE-2025-68156** affecting `expr-lang/expr v1.17.2`. Currently, the Dockerfile downloads pre-compiled CrowdSec binaries which contain the vulnerable dependency. We will implement a multi-stage build following the existing Caddy pattern to compile CrowdSec with patched `expr-lang/expr v1.17.7`. + +**Key Insight:** The current Dockerfile **already has a `crowdsec-builder` stage** (lines 199-244) that builds CrowdSec from source using Go 1.25.5+. However, it does **not patch the expr-lang/expr dependency**.
