CVE-2026-11625

Summary

Bytes::Random::Secure versions through 0.29 for Perl share internal state across forked processes.

When an object is initialised before forking, or when the functional interface is used, 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.

Affected Software

Weaknesses

• CWE-335: CWE-335 Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG)

Workarounds

Apply the patch.

Otherwise, only use the object-oriented interface and ensure that the object is only instantiated in a child process after forking.

Alternatively, use a different module such as Crypt::PRNG, Crypt::SysRandom or Crypt::URandom.
