CVE-2019-25211: Gin mishandles a wildcard at the end of an origin string

parseWildcardRules in Gin-Gonic CORS middleware before 1.6.0 mishandles a wildcard at the end of an origin string, e.g., https://example.community/* is allowed when the intention is that only https://example.com/* should be allowed, and http://localhost.example.com/* is allowed when the intention is that only http://localhost/* should be allowed.

Root Cause Analysis

The CVE description explicitly references 'parseWildcardRules' as the vulnerable function.
The GitHub PR #106 and commit 27b723a show the fix modifies line 138 of cors.go, changing 'o[:i-1]' to 'o[:i]' for wildcard-at-end cases.
Multiple independent reports (PR #57, #106) confirm the pattern matching logic error in this specific function.
The vulnerability manifests in origin validation when processing CORS rules with trailing wildcards, directly tied to this function's string manipulation logic.
