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.
