NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_security package and not the mod_security package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions prior to 2.9.10 contain a denial of service vulnerability similar to GHSA-859r-vvv8-rm8r/CVE-2025-47947. The sanitiseArg (and sanitizeArg - this is the same action but an alias) is vulnerable to adding an excessive number of arguments, thereby leading to denial of service. Version 2.9.10 fixes the issue. As a workaround, avoid using rules that contain the sanitiseArg (or sanitizeArg) action.
