AI-powered 'Code-Diff-Analyzer' found issues on commit 599a5c2.

Path	Line	Severity	Description
sandbox/plugins/test-ppl-frontend/build.gradle	35	high	Unrestricted mavenLocal() repository added. Previously mavenLocal was scoped exclusively to 'org.opensearch.query' group via includeGroup filter. The replacement bare mavenLocal() allows any artifact in the local Maven cache (~/.m2) to shadow remote dependencies, significantly expanding the supply chain attack surface in CI/CD environments where the local cache may be writeable by untrusted processes.
sandbox/build.gradle	49	high	Removal of the restricted mavenLocal repository block (mavenContent { includeGroup 'org.opensearch.query' }) from the root subprojects repositories configuration. This is a repository configuration change that alters dependency resolution behavior across all sandbox subprojects; maintainers should verify the intended resolution order is preserved.
sandbox/plugins/analytics-engine/build.gradle	22	high	Dependency version downgrade: sqlUnifiedQueryVersion changed from '3.7.0.0-SNAPSHOT' to '3.6.0.0-SNAPSHOT'. Downgrading to an older SNAPSHOT introduces a different (older) artifact than was previously validated. Removed comments had explicitly documented why 3.7 was required; this reversal should be verified against the current state of the feature branch.
sandbox/plugins/test-ppl-frontend/build.gradle	38	high	Removal of mavenContent { excludeGroup 'org.opensearch.query' } filter from the OpenSearch Snapshots repository. This filter previously prevented the remote snapshots repo from serving org.opensearch.query artifacts. Its removal changes which remote source resolves this group and should be verified to ensure the correct artifact version is resolved.
sandbox/plugins/analytics-backend-datafusion/build.gradle	19	high	Removal of mavenContent { excludeGroup 'org.opensearch.query' } filter from the OpenSearch Snapshots repository in the analytics-backend-datafusion subproject. As with other subprojects, this changes the dependency resolution path for the org.opensearch.query group and is a repository configuration change that must be verified by maintainers.
