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 · unedited
Citrix Secure Mail for Android before 20.11.0 suffers from Improper Control of Generation of Code ('Code Injection') by allowing unauthenticated access to read data stored within Secure Mail. Note that a malicious app would need to be installed on the Android device or a threat actor would need to execute arbitrary code on the Android device.

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.
