CVE-2022-36944: Fedoraproject Fedora

Critical severity, CVSS 9.8. EPSS: 10.6% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 35 only; version 36 only
• Scala-Lang Scala: from 2.13.0, before 2.13.9 (fixed in 2.13.9)
• Scala-Lang Scala-Collection-Compat: before 2.9.0 (fixed in 2.9.0)
