Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the render process. An attacker can exhaust system resources and cause the PHP process to crash by submitting a specially crafted HTML document containing a high-entropy, oversized image encoded in Base64 and wrapped in specific CSS containers. This leads to excessive memory allocation and CPU usage during rendering, ultimately resulting in process termination.
