CVE-2022-31155 | Unauthorized overwriting of saved searches in Sourcegraph

Sourcegraph is an opensource code search and navigation engine. In Sourcegraph versions before 3.41.0, it is possible for an attacker to delete other users’ saved searches due to a bug in the authorization check. The vulnerability does not allow the reading of other users’ saved searches, only overwriting them with attacker-controlled searches. The issue is patched in Sourcegraph version 3.41.0. There is no workaround for this issue and updating to a secure version is highly recommended.

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:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
