Miggo AIRoot Cause Analysis

  1. Multiple sources (CVE, GHSA, ruby-advisory-db) explicitly identify the foreach function in ext/ccsv.c as the vulnerability location.
  2. The crash backtrace shows memory corruption in ccsv.so with a double free pattern.
  3. The vulnerability manifests specifically during CSV parsing operations handled by this function.
  4. The CWE-415 classification confirms the double free pattern matches the observed behavior.
  5. Though no patch is available, the reproduction case and technical details in Issue #15 demonstrate the function's flawed memory management logic.
