CVE-2026-61500 Rejetto HFS < 3.2.1 Session Forgery via Predictable Signing Key

Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's...
