CVE-2026-103006 Details
Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted, deeply nested request submitted to the aggregation feature of the search API. Elasticsearch contains an uncontrolled recursion weakness in its search aggregation processing. An authenticated user with read access to a single index can submit a specially crafted request containing deeply nested aggregation definitions. Processing this request triggers unbounded recursive execution that exhausts the server process's available resources, causing the affected node to terminate. The node does not recover automatically and requires manual intervention to restore service.

Exploit prediction scoring system (EPSS) score for CVE-2026-103006
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
0.41 Probability of exploitation activity being observed over the next 30 days (34rd percentile)
CVSS score for CVE-2026-103006
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
