NVD · uneditedImproper input validation in Zoom Desktop Client for Windows before 5.14.7 may allow an unauthenticated user to enable an escalation of privilege via network access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceImproper input validation in Zoom Desktop Client for Windows before version 5.14.7 allows an unauthenticated attacker to achieve privilege escalation via network access. The vulnerability stems from the client not properly validating input data, which an attacker can exploit to elevate their privileges on the affected system.
