## 4. Binary Verification
### 4.1 CrowdSec cscli Binary Inspection
**Command**: `go version -m ./cscli_verify | grep expr-lang`
**Results**:
```
dep github.com/expr-lang/expr v1.17.7 h1:Q0xY/e/2aCIp8g9s/LGvMDCC5PxYlvHgDZRQ4y16JX8=
```
**Status**: ✅ **VERIFIED**
**Verification Process**:
1. Extracted cscli binary from charon:patched container
2. Used `go version -m` to inspect embedded Go module info
3. Confirmed expr-lang dependency version matches v1.17.7
4. Hash `h1:Q0xY/e/2aCIp8g9s/LGvMDCC5PxYlvHgDZRQ4y16JX8=` matches official expr-lang v1.17.7 checksum
**Significance**:
This definitively proves that the CVE-2025-68156 remediation (expr-lang upgrade) is present in the production binary. The vulnerable v1.16.9 version is no longer present in the container image.
