How to fix?
There is no fixed version for
fast-string-search is a module that can search substrings in a string by using N-API and boyer-moore-magiclen.
Affected versions of this package are vulnerable to Out-of-bounds Read due to incorrect memory freeing and length calculation for any non-string input as the source. This allows the attacker to read previously allocated memory.
const fss = require('fast-string-search'); fss.indexOf("My password is joke 9", "is"); let res = fss.indexOf(1, "9"); // res will contain the index of "9" from the previous input and not the current one. console.log(res)
