hello experts,

in my code that got fortify scanned, there was a line file.writealltext(pathparam, strdata)...where pathparam is a combination of filename and current directory set somewhere above in the code. This line came under scanner advising to correct the break. I tried using a small method to validate the pathparam value by wrapping the pathparam value inside getfullpath method and if correctly returned used the same in file writealltext.Stilk the vulnerability exists. Kindly advise best way to fix this, if possible by a sample code. Many Thanks.
