Securing JSON-PATCH paths in Spring Boot Data Rest application

stackoverflow.com › questions › 42590027 › securing-json-patch-paths-in-spring-boot-data-rest-application

Seems that current implementation on spring-data-rest converts paths to SpEL to apply values directly on beans. See PatchOperation (v2.5.x).

Consider these options:

Instead of json-patch use json-merge PATCH request to send partial updates (with "application/json" or "application/merge-patch+json" content type). This will respect @JsonIgnore and other Jackson annotations and also treat associations differently.
You can disable "json-patch+json" completely, for example by adding a security filter
You can always create your custom json-patch implementation, if you still need it
Use application-level joining not relying on JPA, i.e. only exposing IDs of the linked entities and providing custom links in your ResourceProcessor.

Additionally, if you're using JPA and Comment.article is annotated with @ManyToOne make sure that there's no cascading on association. Even if the article object is modified with patch it won't be saved together with the comment.

Using JSON Patch in Spring REST APIs | Baeldung

May 11, 2024 - When a patch request with the application/json-patch+json “Content-Type” arrives, Spring Boot uses the default MappingJackson2HttpMessageConverter to convert the request payload to a JsonPatch instance.

Working with JSON Patch vs Merge Patch for Partial Updates in Spring Boot APIs

January 30, 2026 - With Spring Boot 4 and Jackson 3, a controller can still accept a patch document and apply it to a domain object by turning the object into a tree of nodes, applying the patch, then reading the modified tree back into the same type.

There's been a recent fix in Spring Data Rest:

https://github.com/spring-projects/spring-data-rest/issues/2177

The commit that resolves this issue is:

https://github.com/spring-projects/spring-data-rest/commit/5d0687d1a1bb9a84264ecb4cd088907837c382d3

From a quick read this seems to be checking that when applying a JSON patch to an entity a check is done with Jackson that the path should be accessible (read/write).

This should prevent users from being able to specify paths in the JSON patch that aren't normally exposed through POST/GET requests that are mapped directly onto entities through Jackson. I think that if you had marked the article as readable from the comment and the title attribute as writeable then the new code should allow it. Or that's I think what org.springframework.data.rest.webmvc.json.patch.JsonPointerMapping#verify is trying to do.

So if you marked the article on the comment as not being readable through Jackson (@JsonIgnore on the getter) then JSON patch shouldn't allow the title of the article to be set through a comment. The association would still exist, just not be exposed through JSON serialization, I'm not sure if this would cause problems for your application.

The change is released in Spring Data Rest 4.0.0 which is part of Spring Data 2022.0.1 which is in Spring Boot 3.0.2.

Techniques to Apply JSON Patch to JPA Entities in Spring Boot: A Comprehensive Guide | by Anh Trần Tuấn | tuanhdotnet | Medium

April 5, 2025 - JSON Patch is a standard format (RFC 6902) for describing changes to a JSON document. It represents a series of operations that can be applied to modify a JSON object. These operations include add, remove, replace, copy, move, and test.

November 7, 2023 - The Jackson Object mapper isn't capable of serializing/deserializing the new types defined in JSR-353/JSR-374, like the JsonValue and JsonStructure. To configure Jackson for these new types we must first add the following dependency to the project: compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr353', version: '2.10.2' Then we need to create a custom ObjectMapper bean and register the Jackson JSR-353 datatype as a module. In Spring we can create a configuration class to define a new bean:

Alternatively, we could simply annotate the method with @Valid and Bean Validation will take care of performing the the validation on the returned value (the Spring bean may need to be annotated with @Validated to trigger the validation): @Valid public <T> T patch(JsonPatch patch, T targetBean, Class<T> beanClass) { // Convert the Java bean to a JSON document JsonStructure target = mapper.convertValue(targetBean, JsonStructure.class); // Apply the JSON Patch to the JSON document JsonValue patched = applyPatch(patch, target); // Convert the JSON document to a Java bean and return it return mapper.convertValue(patched, beanClass); }

Apparently the body I send to the endpoint has to be an array in order for it to be converted to a JsonPatch object. Changing my body to:

String body = "[{\"op\":\"replace\",\"path\":\"/resursID\",\"value\":\"Jonas\"}]";

solved my problem!

But in the Spring controller this request body will be mapped to a new instance of Book class where alongside the title and totalPage property other properties will also populated as null.

Spring Endpoint to handle Json Patch and Json Merge Patch - Java Code Geeks

java - Handling PATCH requests with JsonPatchHandler in Spring Boot - Stack Overflow

Actually it turned out that there are two types of PATCH requests. The first type are HTTP PATCH requests, which are described here: https://www.rfc-editor.org/rfc/rfc5789 and there: http://restcookbook.com/HTTP%20Methods/patch/. I needed exactly those types of queries and managed to handle them using a Map, as described here: How to do PATCH properly in strongly typed languages based on Spring - example in the simple solution.

The second type of PATCH requests are the JSON ones. They are a little more complicated and are described here: https://www.rfc-editor.org/rfc/rfc6902. They are the ones that are supposed to be handled using JsonPatch and the method I asked in my question.
