Root Cause Analysis

The vulnerability stems from unconstrained execution of jqPathExpressions. The jqNormalizerPatch.Apply function previously executed jq queries without a timeout, allowing specially crafted expressions (like 'until(true == false; [.] + [1])') to consume excessive resources. The NewIgnoreNormalizer function was responsible for creating these vulnerable patches without timeout parameters. The patch adds a JQExecutionTimeout field and context-based execution limits, confirming these were the vulnerable points.
