• Severity: high (CVSS 7.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days

Description

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

How to fix

Upgrade to a fixed version: Scala-Sbt Io 1.9.7; Scala-Sbt Sbt 1.9.7. Check the vendor advisory for mitigations.
