SSC335-GC2063-Face-0b77 Solution Camera: Authentication Bypass Using an Alternate Path or Channel
CVE-2026-8598 is a critical-severity authentication bypass using an alternate path or channel vulnerability in SSC335-GC2063-Face-0b77 Solution Camera from ZkTeco, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V5.0.1.2.20260421 as the first without the flaw, so updating SSC335-GC2063-Face-0b77 Solution Camera to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.51% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update SSC335-GC2063-Face-0b77 Solution Camera to V5.0.1.2.20260421 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
How developers prevent this class of flaw
- Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
