CVE-2024-8013 | CSFLE and Queryable Encryption self-lookup may fail to encrypt values in subpipelines

A bug in query analysis of certain complex self-referential $lookup subpipelines may result in literal values in expressions for encrypted fields to be sent to the server as plaintext instead of ciphertext. Should this occur, no documents would be returned or written. This issue affects mongocryptd binary (v5.0 versions prior to 5.0.29, v6.0 versions prior to 6.0.17, v7.0 versions prior to 7.0.12 and v7.3 versions prior to 7.3.4) and mongo_crypt_v1.so shared libraries (v6.0 versions prior to 6.0.17, v7.0 versions prior to 7.0.12 and v7.3 versions prior to 7.3.4) released alongside MongoDB Enterprise Server versions.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
2.2 3.1 LOW
CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
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:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
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.

3.3 3.1 LOW

Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
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:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
