Affected package

jsrsasignnpm
Affected
<11.1.1
Fixed in
11.1.1
Update to the fixed version for your release line, for example:npm install jsrsasign@11.1.1

Details

Versions of the package jsrsasign before 11.1.1 are vulnerable to Infinite loop via the bnModInverse function in ext/jsbn2.js when the BigInteger.modInverse implementation receives zero or negative inputs, allowing an attacker to hang the process permanently by supplying such crafted values (e.g., modInverse(0, m) or modInverse(-1, m)).

Is GHSA-8g7p-jf3g-gxcp in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected jsrsasign, and gives you the command that fixes it.
