Functions ¶
func CheckBlockedExtension ¶
CheckBlockedExtension returns an error if the filename has a blocked extension.
func CheckInlineImageFormat ¶
CheckInlineImageFormat validates that the file is an allowed inline image format by checking both extension and content-sniffed MIME type. Both must match the whitelist to prevent extension spoofing and MIME forgery. On success it returns the detected MIME type; callers MUST use this as the final Content-Type instead of trusting any user-supplied or inherited value.
