Endor Labs explains "upgrade impact analysis," a call-graph-based technique that diffs a dependency's current and target versions, overlays the changed symbols onto an application's call graph, and determines whether any code path actually reaches the changed code before a version bump is merged. It categorizes upgrade risk into breaking API changes, transitive dependency conflicts, and silent behavioral regressions, and proposes a decision framework (upgrade, backport a patch, or wait) based on reachability and blast-radius scoring so teams can fix CVEs without breaking builds.
TL;DR Endor Labs describes call-graph-based "upgrade impact analysis" that uses reachability to predict whether a dependency version bump will break your build before you merge it.
