In Linaro Automated Validation Architecture (LAVA) before 2022.11, users with valid credentials can submit crafted XMLRPC requests that cause a recursive XML entity expansion, leading to excessive use of memory on the server and a Denial of Service.
The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.
