CVE-2026-92749
SafeLine through 9.4.1 derives the management console session-signing secret from a time-seeded math/rand generator, allowing attackers to reconstruct the key offline.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SafeLine through 9.4.1 derives the management console session-signing secret from a time-seeded math/rand generator, allowing attackers to reconstruct the key offline. Unauthenticated remote attackers who can bound the install timestamp can regenerate the secret and forge valid administrator session cookies to gain control of protected sites.
