Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to use of externally controlled input to select classes or code in JDKFromStringDeserializer.NioPathHelper.deserialize when deserializing untrusted JSON into a java.nio.file.Path field. A remote attacker can supply a specially crafted URI scheme to drive FileSystemProvider resolution and cause a denial of service.

Exploitation occurs during readValue, and meaningful side effects beyond the reported availability impact depend on the presence of a side-effecting third-party FileSystemProvider on the classpath.
