…mand Implement dynamic runtime template parsing and validation inside HttpCommand to protect Discovery REST clients from path traversal and parameter injection exploits. Specifically, this change: - Rejects query (?) and fragment (#) characters in path parameter values. - Rejects slashes (/) and dots (. or ..) in simple path variables (standard wildcards). - Validates path traversals in reserved path variables (+ or #, double wildcards) using a segment-boundary traversal validation algorithm. In addition to the validation logic, this commit includes: - Ruby style modernization: cleaned up and auto-corrected string quote style to favor single quotes where appropriate. - Formatted long stub requests to follow style guidelines. Note: If the canonical specification is updated to favor the simpler alternative, this implementation can be easily simplified to "Fail always if dots are found in a double-wildcard value" by replacing the segment-traversal logic with a simple check for any "." or ".." substring.
