CVE-2022-23643Network attack vector

Private-code string disclosure via Code Monitor oracle

Published Feb 15, 2022 · Updated Apr 23, 2025

Information disclosure in Sourcegraph 3.35.0 through 3.35.1 and 3.36.0 through 3.36.2 allows remote authenticated users to infer private-code strings. Code Monitoring reports whether a supplied search string exists in source code that the monitor creator cannot access, creating an observable result oracle. Exploitation requires an authenticated account and many crafted Code Monitors, and can expose formatted secrets such as API keys without granting direct repository access.
