The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD.

WAF and other mitigations

Can a WAF block it? No. The attack needs local access to the machine, so a WAF is not on its path.

Also consider: patch · per-resource ACL

Based on the attack vector (local or physical access). We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions

Is CVE-2026-120815 being exploited?

Not confirmed. CVE-2026-120815 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked.

How severe is CVE-2026-120815?

CVE-2026-120815 is rated High with a CVSS score of 8.6. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2026-120815?

Not known from our data. No patch reference has been recorded for CVE-2026-120815, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.

What does CVE-2026-120815 affect?

CVE-2026-120815 affects MongoDB Server (authorization enabled). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

What should I do about CVE-2026-120815?

Apply vendor fixes when available; restrict localhost access, rotate credentials, enable monitoring.
