## Affected

- dbgate: through 7.2.6

## Description

DbGate fails to validate jslid parameters in the jsldata controller, allowing authenticated users to read and write arbitrary files via file:// scheme resolution. Attackers can exploit getJslFileName() to bypass directory containment and access sensitive files including encrypted database credentials stored in connections configuration.

## What to do
