CVE-2021-43823

Name of the Vulnerable Software and Affected Versions: Sourcegraph versions prior to 3.33.2

Description: The issue allows an authenticated but unauthorized actor to guess strings in private source code through a side-channel attack. This affects the Saved Searches and Code Monitoring features. A successful attack requires creating many Saved Searches or Code Monitors to confirm the existence of a specific string, potentially allowing an attacker to guess formatted tokens like API keys.

Recommendations: For versions prior to 3.33.2, upgrade to version 3.33.2 or a later version to secure your system. If upgrading is not possible, disable Saved Searches and Code Monitors as a temporary workaround.
