Miggo AIRoot Cause Analysis

The vulnerability chain involves three key functions: 1) GetApplicationUrlFromCurrentRequest directly uses the untrusted Host header to build URLs. 2) EnsureApplicationMainUrl persists this value system-wide. 3) ConstructCallbackUrl uses the poisoned URL to generate reset links. The advisory's code snippets and attack flow analysis explicitly reference these functions' roles in the exploit chain. The first two functions enable persistent poisoning (CVE-2022-22690), while the third enables token leakage (CVE-2022-22691).
