file_open in Tryton 3.x and 4.x through 4.2.2 allows remote authenticated users with certain permissions to read arbitrary files via a same root name but with a suffix attack. NOTE: This vulnerability exists because of an incomplete fix for CVE-2016-1242.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
