Summary

Tamery (formerly Conar) from 0.32.0 before 0.99.0 contains a broken authorization flaw in the cloud sync API connectionsResources.create handler (CWE-639). An authenticated user who owns one connection can include another user's connectionId in a batch request to insert resource rows with attacker-chosen names under that victim's connection. The victim's client then lists these attacker-named resources.
