Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Neethi versions before 3.2.2 are vulnerable to a denial of service through algorithmic complexity in policy normalization. A specially crafted WS-Policy document can trigger an exponential expansion that exhausts the JVM heap, so an attacker who can supply such a document can crash or stall the service. Upgrade Neethi to version 3.2.2, which limits the number of normalized policy alternatives.
