Path	Line	Severity	Description
build.gradle	9	high	Dependency version change: default opensearch_version bumped from 3.8.0-SNAPSHOT to 3.9.0-SNAPSHOT. SNAPSHOT versions resolve against mutable artifact repositories, making them particularly susceptible to supply chain substitution or namespace hijacking. Maintainers should verify the 3.9.0-SNAPSHOT artifact is published to the expected repository and that no unauthorized artifact exists at that coordinate.
