CVE-2026-11702

Bytes::Random::Secure::Tiny versions through 1.011 for Perl share internal state across forked processes. When an object is initialised before forking, then the internal state for the PRNG is shared across processes and identical random streams will be produced. Secrets generated in multiprocess applications are predictable across processes.

Summary		(es) Las versiones de Bytes::Random::Secure::Tiny hasta la 1.011 para Perl comparten estado interno entre procesos bifurcados. Cuando un objeto se inicializa antes de la bifurcación, entonces el estado interno para el PRNG se comparte entre procesos y se producirán flujos aleatorios idénticos. Los secretos generados en aplicaciones multiproceso son predecibles entre procesos.
