Description

All versions of the package node-stringbuilder are vulnerable to Out-of-bounds Read due to incorrect memory length calculation, by calling ToBuffer, ToString, or CharAt on a StringBuilder object with a non-empty string value input. It’s possible to return previously allocated memory, for example, by providing negative indexes, leading to an Information Disclosure.
