CVE-2026-88385
Description
A flaw was found in mxml. A remote attacker could cause a Denial of Service (DoS) by supplying specially crafted, malformed XML data to an application utilizing the library. When handling parsing errors, the parser fails to release certain allocated text nodes, leading to a persistent memory leak on each parsing attempt. Over repeated requests, this uncontrolled memory accumulation can exhaust system memory and result in application unavailability.
