CVE-2021-32787 | Low risk information disclosure in Sourcegraph

Sourcegraph is a code search and navigation engine. Sourcegraph before version 3.30.0 has two potential information leaks. The site-admin area can be accessed by regular users and all information and features are properly protected except for daily usage statistics and code intelligence uploads and indexes. It is not possible to alter the information, nor interact with any other features in the site-admin area. The issue is patched in version 3.30.0, where the information cannot be accessed by unprivileged users. There are no workarounds aside from upgrading.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
3.1 3.1 LOW
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
