CVE-2026-102682 in pipecat
Summary
by MITRE • 10/14/2026
Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. From 0.0.98 until 1.6.0, the pipecat-ai package's built-in development runner exposes unauthenticated endpoints including /start, /daily, and /daily-dialin-webhook that can create bot sessions and Daily rooms. The runner binds to localhost by default and is intended only for local development, so exploitation requires an operator to expose it to untrusted traffic through --host 0.0.0.0, a published port, or a tunnel without access controls. An unauthenticated caller can consume local resources and third-party quotas and, depending on configuration, receive a room URL and join token. Version 1.6.0 adds a prominent development-runner banner and documentation that clarifies the unauthenticated boundary and directs production deployments to an authenticated dispatcher or managed runtime, while the endpoint behavior remains by design. This issue is fixed in version 1.6.0.

The vulnerability identified within the Pipecat framework stems from a misconfiguration of its built-in development runner, which was designed exclusively for local testing and debugging purposes but inadvertently exposes sensitive operational endpoints to potential external access under specific deployment conditions. From versions 0.0.98 through 1.6.0, the package includes an HTTP server that binds by default to localhost, a secure practice intended to restrict access to only processes running on the same machine. However, this security boundary is easily bypassed if an operator explicitly configures the runner to listen on all network interfaces using the --host 0.0.0.0 flag, publishes the port through a firewall or cloud service configuration, or utilizes a tunneling solution that forwards external traffic to the local development server without implementing additional access controls such as IP whitelisting or authentication middleware. This architectural oversight creates an unauthenticated attack surface where any entity with network reachability to the exposed endpoint can interact directly with the application logic intended for internal use only.
The technical flaw centers on the exposure of critical endpoints including /start, /daily, and /daily-dialin-webhook, which are responsible for initiating bot sessions and provisioning rooms within the Daily video conferencing infrastructure. When an unauthenticated caller accesses these endpoints, they can trigger resource-intensive operations that consume local computational resources such as CPU cycles and memory on the host machine running the Pipecat instance. Furthermore, depending on the specific configuration of the application, successful exploitation allows the attacker to create new bot sessions and generate valid room URLs along with join tokens for Daily rooms. This capability effectively permits an unauthorized actor to hijack third-party quotas associated with the victim's account or organization, leading to potential financial impact through excessive usage charges and operational disruption by flooding shared communication channels with unsolicited session requests.
From a classification perspective, this vulnerability aligns with CWE-284 Improper Access Control, as the system fails to restrict access to functions that require higher privileges for production environments. It also relates to CWE-798 Use of Hard-coded Credentials if any default authentication tokens are involved in the room creation process, although the primary issue is the lack of network-level or application-level authorization checks on development-specific endpoints. In terms of adversary behavior, this scenario maps to ATT&CK technique T1505 Server Software Component, where an attacker leverages a legitimate software component for malicious purposes by exploiting its exposed functionality without needing to inject custom code or exploit a traditional buffer overflow. The impact is primarily characterized as Denial of Service through resource exhaustion and potential privacy violations if the generated rooms are used to intercept communications intended for authorized participants.
The resolution implemented in version 1.6.0 addresses this issue not by removing the endpoints, which remain necessary for development workflows, but by enhancing visibility and guidance around their usage. The update introduces a prominent banner warning users that they are running an unauthenticated development server, thereby increasing operator awareness of the security implications. Additionally, updated documentation explicitly clarifies the unauthenticated boundary and strongly directs production deployments to utilize authenticated dispatchers or managed runtimes that enforce proper identity verification before allowing session creation. To mitigate this risk in environments where older versions must remain operational, operators should ensure that the development runner is never bound to 0.0.0.0 unless strictly necessary for local testing behind a secure loopback interface. If external access is required during development, it is imperative to implement network-level controls such as firewall rules restricting source IPs or deploy an authentication proxy in front of the service to validate requests before they reach the Pipecat application logic.
