CVE-2026-33191 HIGH PATCH This Week

Null byte injection in the UDM's Nudm_SubscriberDataManagement API allows unauthenticated remote attackers to crash the service by embedding URL-encoded %00 characters in the supi parameter, triggering unhandled parsing errors and denial of service. The vulnerability stems from improper input validation that permits control characters to reach Go's URL parser, which rejects them with a 500 error instead of sanitizing the input upstream. A patch is available.
