# Summary [NIFI-10871](https://issues.apache.org/jira/browse/NIFI-10871) Adds a new Servlet Filter to the application Spring Security Filter Chain configuration for skipping Cross-Site Request Forgery processing on HTTP requests replicated between cluster nodes. The introduction of CSRF mitigation using the standard Spring Security `CsrfFilter` causes the application to generate and set a `__Secure-Request-Token` cookie on HTTP responses. This is not necessary for requests replicated from one cluster node to another. As a result of the current behavior, requests to cluster nodes can return intermittent HTTP 403 responses when a client web browser sends mismatched `__Secure-Request-Token` Cookie and `Request-Token` Header values. Skipping CSRF token generation for cluster replicated requests avoids introducing a new value for the `__Secure-Request-Token` Cookie, which resolves intermittent HTTP 403 responses in clustered deployments. The new `SkipReplicatedCsrfFilter` matches HTTP requests based on the presence of the custom `X-RequestTransactionId`, which the standard Request Replicator applies to replicated requests. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [X] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [X] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [X] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [X] Pull Request based on current revision of the `main` branch - [X] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `mvn clean install -P contrib-check` - [X] JDK 8 - [ ] JDK 11 - [ ] JDK 17 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
