|---|
| विवरण | CowAgent 2.1.3 has a denial of service vulnerability in the browser tool workflow.
The browser tool accepts prompt-controlled wait/evaluate operations and runs them through a process-wide shared BrowserService backed by a single Playwright worker thread. When a caller or upstream client times out, the underlying Playwright operation is not cancelled.
An attacker who can influence an agent task through prompt injection can cause the agent to invoke a long browser wait or evaluate operation. This can keep the shared browser thread occupied after the client timeout, causing later normal browser operations to queue and fail within normal deadlines.
