Machine-written summary

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

Spring HATEOAS versions 1.5.0 through 1.5.6, 2.3.0 through 2.3.4, 2.4.0 through 2.4.1, 2.5.0 through 2.5.2, and 3.0.0 through 3.0.3 keep an unbounded static cache of link relation instances keyed on attacker-supplied strings. The source gives few details about how an attacker reaches this cache, but repeated attacker-controlled input can grow it until the heap is exhausted. Upgrade spring-hateoas to 3.0.4 or 2.5.3, or to a later release in your line.
