Answer in brief
CVE-2026-31846 records a Unknown severity vulnerability in Unauthenticated Credential Disclosure via /goform/ate in Nexxt Nebula 300+. The current sources do not mark it as known exploited. The current feed maps Nexxt Solutions/Nebula 300+ / Tenda F3 V2.0 Firmware (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Missing authentication in the /goform/ate endpoint in Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 allows an adjacent unauthenticated attacker to retrieve sensitive device information, including the administrator password. An attacker can decode this value to obtain valid administrative credentials and authenticate to the device.
