The issue can be triggered by a broken multipart\/form-data request lacking an end boundary to any of OctoPrint&#8217;s endpoints implemented through the octoprint.server.util.tornado.UploadStorageFallbackHandler request handler. The request handler will get stuck in an endless busy loop, looking for a part of the request that will never come. As Tornado is single-threaded, that will effectively block the whole web server. The vulnerability has been patched in version 1.11.2.<br \/>\n<br \/>\n<strong>Severity:<\/strong> 6.5 | MEDIUM<br \/>\n<br \/>\nVisit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-48879 Published : June 10, 2025, 4:15 p.m. | 45\u00a0minutes ago Description : OctoPrint versions up until and including 1.11.1 contain a vulnerability that allows any unauthenticated attacker to send a manipulated broken multipart\/form-data request to OctoPrint and through that make the web server component become unresponsive.
