Machine-written summary

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

Spring Data REST (spring-data-rest-core) is affected in versions 5.0.0 through 5.0.5, 4.5.0 through 4.5.11, 4.4.0 through 4.4.14, 4.3.0 through 4.3.16, and 3.7.0 through 3.7.19. When a persistent entity has a Map-typed property, the map key taken from a JSON Patch request path is inserted into a SpEL expression without sanitization, so an attacker who can send JSON Patch requests may be able to inject SpEL expressions. Upgrade to 5.0.6 or 4.5.12, or to a later fixed release if on another line.
