    Improper Input Validation

    matrix-synapse is an ecosystem for open federated Instant Messaging and VoIP.

    Affected versions of this package are vulnerable to Improper Input Validation. A malicious server can disrupt the normal operation and prevent the application from federating with other servers by crafting events that exploit this flaw.

    Note:

    This is only exploitable in environments where federation is enabled.

    How to fix Improper Input Validation?

    Upgrade matrix-synapse to version 1.127.1 or higher.

    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.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade matrix-synapse to version 1.120.2 or higher.
