Vulnerability details
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in Spring data binding infrastructure when applying user-supplied property paths onto a target object. A remote attacker can supply a property path with an arbitrarily large index into a nested sub-property to cause a denial of service.
Exploitation requires the target object to contain a self-populating list implementation as a property, and the list element type must expose sub-properties.
