Description
A flaw was found in the mod_security2 Apache2 module. Versions up to and including 2.9.8 are vulnerable to denial of service in one special case. In stable released versions, when the payload's content type is `application/json`, at least one rule performs a `sanitiseMatchedBytes` action, a security control that automatically cleans or neutralizes specific patterns of potentially harmful data that prevents malicious input from reaching systems or sensitive information from leaking.
