CVE-2025-3085 | MongoDB Server running on Linux may allow unexpected connections where intermediate certificates are revoked

A MongoDB server under specific conditions running on Linux with TLS and CRL revocation status checking enabled, fails to check the revocation status of the intermediate certificates in the peer's certificate chain. In cases of MONGODB-X509, which is not enabled by default, this may lead to improper authentication. This issue may also affect intra-cluster authentication. This issue affects MongoDB Server v5.0 versions prior to 5.0.31, MongoDB Server v6.0 versions prior to 6.0.20, MongoDB Server v7.0 versions prior to 7.0.16 and MongoDB Server v8.0 versions prior to 8.0.4. Required Configuration : MongoDB Server must be running on Linux Operating Systems and CRL revocation status checking must be enabled

Base score Version Severity Vector Exploitability Impact Score source
8.1 3.1 HIGH
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H 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:N)
No account or special rights needed—anonymous or random user is enough.
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:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
