Each call consumes approximately 30 bits of PRNG state, and the Mersenne Twister internal state is approximately 19,937 bits, so an attacker who observes approximately 334 session IDs (for example via the X-Urwid-ID HTTP response header) can fully reconstruct the internal state and predict all past and future session IDs (Path B).

With a valid session ID, an attacker can read the victim&#39;s terminal screen via the polling endpoint, inject keystrokes into the victim&#39;s session (yielding OS-level code execution with the session owner&#39;s privileges if the session runs a shell), and inject exit sequences or flood the FIFO to terminate or crash the session.
