Detailsinfo

A vulnerability, which was classified as problematic, was found in Elastic Elasticsearch up to 8.19.19/9.4.4. Affected is an unknown code block of the component Intervals Query. The manipulation with an unknown input leads to a recursion vulnerability. CWE is classifying the issue as CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. This is going to have an impact on availability. CVE summarizes:

Elasticsearch does not apply its configurable input length restriction to a user-supplied pattern accepted by an intervals query. Compiling a deeply nested pattern drives unbounded recursion that exhausts the thread stack and raises a fatal error, terminating the Elasticsearch node process and causing a denial of service for that node. An authenticated user holding only read-only privileges on a single searchable index can trigger the condition with one small search request.

The advisory is shared for download at discuss.elastic.co. This vulnerability is traded as CVE-2026-72679 since 08/10/2026. The exploitability is told to be easy.
