CVE-2022-22781
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Zoom Client for Meetings for MacOS (Standard and for IT Admin) prior to version 5.9.6 failed to properly check the package version during the update process. This could lead to a malicious actor updating an unsuspecting user’s currently installed version to a less secure version.
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 · high confidenceThe Zoom Client for Meetings for MacOS versions prior to 5.9.6 contain a vulnerability in the update mechanism that fails to properly validate package versions during the update process. This improper validation allows a malicious actor to potentially force an update to a less secure version of the software, downgrading the victim's installation.
