A vulnerability in OpenSearch allows attackers to cause Denial of Service (DoS) by submitting complex query_string inputs.
This issue affects all OpenSearch versions between 3.0.0 and < 3.3.0 and OpenSearch < 2.19.4.
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 61% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
