Elasticsearch 8.19.x < 8.19.20 / 9.4.x < 9.4.5 / 9.5.x < 9.5.1 Multiple Vulnerabilities (ESA-2026-80 / ESA-2026-123)

The version of Elasticsearch installed on the remote host is 8.19.x prior to 8.19.20, or 9.4.x prior to 9.4.5, or 9.5.x prior to 9.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the ESA-2026-80 and ESA-2026-123 advisories. - The native inference process that...

CVE-2026-72642

The native inference process that Elasticsearch uses to evaluate uploaded machine learning models accepts a model operation that computes a memory address from an offset supplied inside the model, without validating that the offset stays within the bounds of the underlying storage. A user with th...

CVE-2026-72642

The CVE notes a flaw in Elasticsearch’s native ML inference where a model operation computes a memory address from an offset without bounds checking, enabling heap corruption that can crash the inference process and potentially allow arbitrary code execution within that process. Affected configur...
