Machine-written summary

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

Spring Data REST's spring-data-rest-core package is affected in versions 3.7.19 and earlier, 4.3.0 through 4.3.16, 4.4.0 through 4.4.14, 4.5.0 through 4.5.11, and 5.0.0 through 5.0.5. Its JSON Patch implementation does not apply the write-access filter to intermediate segments of multi-segment JSON Pointer paths, so an attacker who can send JSON Patch requests may be able to modify properties that should be restricted. Upgrade to 5.0.6 or 4.5.12, or to a later fixed release in your line; the source gives few other details.
