Overview

github.com/sourcegraph/sourcegraph/cmd/frontend/graphqlbackend is a code search and navigation engine.

Affected versions of this package are vulnerable to Access Restriction Bypass. Strings in private source code could be guessed by an authenticated but unauthorized actor. This issue affects the Saved Searches and Code Monitoring features. A successful attack would require an authenticated bad actor to create many Saved Searches or Code Monitors to receive confirmation that a specific string exists. This could allow an attacker to guess formatted tokens in source code, such as API keys.
