NewCVE-2024-52805 (opens in a new tab)How to fix?
Upgrade matrix-synapse to version 1.120.2 or higher.
Overview
matrix-synapse is an ecosystem for open federated Instant Messaging and VoIP.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the improper handling of multipart/form-data content types. An attacker can amplify denial of service attacks by sending crafted requests that transiently increase memory consumption.
Workaround
This vulnerability can be mitigated by limiting request sizes or blocking the multipart/form-data content type before the requests reach the application, or by setting a low max_upload_size.
