8.1High
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. 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.
What this means for your business
- An attacker can use it remotely, over a network, without a login, and without anyone at your company clicking anything.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
