CVE-2023-46122: Scala-SBT Io

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Scala-SBT Io: from 1.0.0, before 1.9.7 (fixed in 1.9.7)
• Scala-SBT SBT: from 0.3.4, before 1.9.7 (fixed in 1.9.7)
