BIT-ELASTICSEARCH-2026-102408 Inefficient Regular Expression Complexity in Elasticsearch Leading to Denial of Service

Inefficient Regular Expression Complexity CWE-1333 in Elasticsearch can lead to denial of service via Regular Expression Exponential Blowup CAPEC-492. The ES|QL CHUNK function's recursive chunking strategy accepts a list of user-supplied regular expressions used as text-splitting separators,...

Elasticsearch 8.19.x < 8.19.22 / 9.1.x / 9.3.8 / 9.4.x < 9.4.8 / 9.5.x < 9.5.5 DoS (ESA-2026-189)

The version of Elasticsearch installed on the remote host is prior to 8.19.22, 9.4.8, or 9.5.5. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-189 advisory. - Inefficient Regular Expression Complexity CWE-1333 in Elasticsearch can lead to denial of service via Regular...

CVE-2026-102408

A flaw was found in Elasticsearch. An authenticated attacker with read access to an index can cause a Denial of Service DoS by submitting queries containing specially crafted regular expressions to the ES|QL CHUNK function. Because the component does not properly restrict regular expression...
