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