sbt 1.9.6 and earlier: arbitrary file write via IO.unzip in zip/JAR
CVE-2023-46122 Published on October 23, 2023

Arbitrary file write via archive extraction (Zip Slip) vulnerability in sbt
sbt is a build tool for Scala, Java, and others. Given a specially crafted zip or JAR file, `IO.unzip` allows writing of arbitrary file. This would have potential to overwrite `/root/.ssh/authorized_keys`. Within sbt's main code, `IO.unzip` is used in `pullRemoteCache` task and `Resolvers.remote`; however many projects use `IO.unzip(...)` directly to implement custom tasks. This vulnerability has been patched in version 1.9.7.
