Uncontrolled Recursion in Elasticsearch Wildcard Matching Leading to Denial of Service (CVE-2026-72636)CVE-2026-72636 0 CVE-2026-72636 is a medium severity vulnerability in Elasticsearch affecting versions 8.0.0 up to but not including 8.19.20 and 9.0.0 up to but not including 9.4.5. It involves uncontrolled recursion in the wildcard matching helper, which can cause a denial of service by exhausting the thread stack and shutting down the node. This occurs when a search request contains a wildcard pattern with many wildcard groups evaluated against a long name, leading to a stack overflow that Elasticsearch treats as unrecoverable.
