DescriptionCVE.org

A vulnerability was detected in 2FastLabs agent-squad up to 1.1.4. Affected by this vulnerability is the function AgentSquad.routeRequest of the file agent-squad/typescript/src/orchestrator.ts of the component Streaming Agent Response Workflow. The manipulation results in resource consumption. It is possible to launch the attack remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Uncontrolled resource consumption in 2FastLabs agent-squad up to version 1.1.4 allows a low-privileged remote attacker to degrade or deny service by manipulating the streaming agent response workflow through the AgentSquad.routeRequest function in orchestrator.ts. A public proof-of-concept exploit is available on GitHub, and the project maintainers had not responded to the disclosure at time of analysis, meaning no patch exists. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold low-privilege authenticated access to the agent-squad deployment (PR:L per CVSS 4.0) - specifically, the ability to issue requests to any endpoint that invokes `AgentSquad.routeRequest` in the streaming agent response workflow. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L) confirms a remotely exploitable, low-complexity flaw requiring only low privileges - any authenticated user of an agent-squad deployment can trigger the DoS without elevated access or special tooling. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch has been identified at time of analysis - maintainers had not responded to the coordinated disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
