Issue: cfn-lint 0.49.1 does not catch `/` as an invalid character in a Mapping element name *cfn-lint version: cfn-lint 0.49.1* *cfn-lint did not catch `/` as an invalid character in a Mapping element name* cfn-lint passed successfully with this mapping included in the template: ```yaml Mappings:

Files to edit

src/cfnlint/helpers.py

Approach: Update the REGEX_ALPHANUMERIC constant in helpers.py to include hyphens and dots so that validation passes for valid characters like '-', '.', while still rejecting invalid ones like '/'. Ensure the regex allows alphanumerics plus '-' and '.' characters only.

Finish summary: Fixed the regex pattern for validating mapping keys in CloudFormation templates. Updated REGEX_ALPHANUMERIC in src/cfnlint/helpers.py from '^[a-zA-Z0-9]*$' to '^[a-zA-Z0-9\-\.]*$' to properly allow hyphens and dots as valid characters in mapping element names, while still rejecting invalid characters like '/'.
