Description
In
extensions/browser/src/browser/chrome-mcp.ts, CDP message correlation andsleepTimeoutawait paths fail to reject if the target Chrome instance crashes during a paused breakpoint event. The promises remain pending indefinitely, leaking memory and halting the agent's browser automation flow.Impact
Agent halts indefinitely (impact:session-state) and memory leaks occur when Chrome crashes unexpectedly.
