CVE-2022-36944
Critical 9.8
In plain English
A critical-severity unsafe deserialization in the org.scala-lang:scala-library package (Maven). Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 11.0% (higher than 96% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code. Fixed versions are available - upgrade the affected package.
Official description
Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be exploited. There is only a risk in conjunction with Java object deserialization within an application. In such situations, it allows attackers to erase contents of arbitrary files, make network connections, or possibly run arbitrary code (specifically, Function0 functions) via a gadget chain.
