CVE-2025-26326Public exploitNetwork attack vector

Remote system takeover via guessable shared keys

Published Feb 28, 2025 · Updated Mar 13, 2025

Improper authentication in NVDA Remote 2.6.4 and Tele NVDA Remote 2025.3.3 allows remote attackers to take control via a guessed key. The add-ons treat possession of a user-chosen shared key as sufficient authentication and permit trial-and-error guesses without separate approval or computer verification. Exploitation requires a reachable relay or direct connection, an enabled control mode, and a known or guessed key; control permits command execution and file modification.
