Management access via undisclosed authentication bypass
Published Apr 29, 2026 · Updated Apr 29, 2026
Authentication bypass in SonicWall SonicOS allows attackers to access restricted management interface functions from an adjacent network. SonicWall has not published the affected functions, the specific access-control decision that fails, or the request sequence that reaches them. Exploitation requires adjacent-network access and user interaction; the reported consequence includes unauthorized management actions, but its exact scope remains undisclosed.
