Miggo AIRoot Cause Analysis
The vulnerability stems from improper origin validation in CORS handling. The isOriginAllowed function previously used regex patterns compiled by compileRegexps from AllowedDomains, allowing partial matches. The patched commit (fd3c327) replaces regex matching with exact string comparisons and removes compileRegexps, confirming these functions' role in the vulnerability. The CWE-639 description and commit message both indicate the root cause was insecure domain matching logic.
