Vulnerability details
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in the image-transform endpoint in AssetsService.getAsset when processing user-supplied width and height parameters on GET /assets/<id>. A remote attacker can send a specially crafted request to cause a denial of service.
