There is no fixed version for RHEL:7 evolution-data-server-tests.

NVD Description

Note: Versions mentioned in the description apply only to the upstream evolution-data-server-tests package and not the evolution-data-server-tests package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in evolution-data-server. Calendar events containing a file:// URI in their ATTACH property automatically read the targeted local file, base64-encode its contents and upload it back to the server when the event is saved. There are no file path restrictions or checks to verify whether the attachment originally came from the server or was added locally. This allows an attacker with access to a shared CalDAV calendar to exfiltrate arbitrary files the user has access to when interacting with malicious calendar events.
