AI analysisSummaries by Vani AI
An input and authorization validation flaw in Gaia Portal backend handlers lets an authenticated, non-administrative user run privileged operations that should be limited to administrators. The attacker must already have a low-privilege account and reach the portal from an adjacent network; no user interaction is required. Successful use yields high confidentiality and integrity impact, with no availability impact stated. Check Point has not listed affected builds or fixed versions.
What to do: Apply Check Point's update for CVE-2026-107484. No workaround is named.
