Miggo AIRoot Cause Analysis

The vulnerability stemmed from HTTParty's YAML parsing implementation. The commit 53a8124 removed YAML support entirely by deleting: 1) MIME type mappings for YAML in SupportedFormats, 2) the yaml method that called YAML.load(body). YAML.load with untrusted input is known to be dangerous as it can instantiate arbitrary Ruby objects. The CVE description explicitly references YAML type conversion vulnerabilities, and the patch removes these YAML-handling functions, confirming their role in the vulnerability.
