Summary
A vulnerability has been found in Dapr that allows bypassing API token authentication. An attacker could craft a well-formed HTTP request that is accepted by Dapr, even if the API token is invalid or missing.
Risk Assessment
Organizations using Dapr with API token authentication enabled are at risk of unauthorized access to their applications. This could lead to serious security breaches and data loss.
Recommendation
It is recommended to upgrade Dapr to version 1.10.9 or 1.11.2 to mitigate this vulnerability. Additionally, consider reviewing the security configurations of applications using Dapr.
Original NVD description (English source)
Dapr is a portable, event-driven, runtime for building distributed applications across cloud and edge. A vulnerability has been found in Dapr that allows bypassing API token authentication, which is used by the Dapr sidecar to authenticate calls coming from the application, with a well-crafted HTTP request. Users who leverage API token authentication are encouraged to upgrade Dapr to 1.10.9 or to 1.11.2. This vulnerability impacts Dapr users who have configured API token authentication. An attacker could craft a request that is always allowed by the Dapr sidecar over HTTP, even if the `dapr-api-token` in the request is invalid or missing. The issue has been fixed in Dapr 1.10.9 or to 1.11.2. There are no known workarounds for this vulnerability.
