KDE KCron through 21.12.2 uses a temporary file in /tmp when saving, but reuses the filename during an editing session. Thus, someone watching it be created the first time could potentially intercept the file the following time, enabling that person to run unauthorized commands.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
