CWE-494 · CNA: checkpoint · CVSS v3.1 · 3 references · KEV due April 16, 2026

Description

TrueConf Client downloads application update code and applies it without performing verification. An attacker who is able to influence the update delivery path can substitute a tampered update payload. If the payload is executed or installed by the updater, this may result in arbitrary code execution in the context of the updating process or user.
