medium Tenable Cloud Security Plugin ID 437154

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - NiceGUI is a Python-based UI framework. From versions v2.10.0 to 3.4.1, an unauthenticated attacker can
 exhaust Redis connections by repeatedly opening and closing browser tabs on any NiceGUI application using
 Redis-backed storage. Connections are never released, leading to service degradation when Redis hits its
 connection limit. NiceGUI continues accepting new connections - errors are logged but the app stays up
 with broken storage functionality. This issue has been patched in version 3.5.0. (CVE-2026-21874)
