What to check
- Applies to
- The 16 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR published an advisory (CERTFR-2026-AVI-1169) covering multiple vulnerabilities discovered in MongoDB, affecting a broad range of official drivers (C, C#, C++, Go, Java, PHP, Python, Ruby, Rust) and the Core Server itself. The flaws, tracked across 15 distinct CVEs, allow an attacker to cause remote denial of service, breach data confidentiality, and compromise data integrity. No indication of active exploitation in the wild is mentioned in the advisory.
Affected versions span nearly all MongoDB driver ecosystems and server releases prior to 7.0.43, 8.0.32, 8.3.11, and 9.1.0-rc0, along with driver-specific version thresholds (e.g., C Driver <1.30.10/<2.5.3, Python Driver <4.18.1, Java Driver <5.11.1, etc.). This wide scope indicates the vulnerabilities likely stem from shared underlying libraries or protocol handling logic used across the driver implementations.
Defenders running MongoDB deployments or applications using any of the listed driver versions should consult the referenced MongoDB Jira security bulletins and CVE records to identify exact impact per component, then upgrade to the fixed versions noted in the advisory. Given the number of affected components (drivers plus core server) and the mix of confidentiality, integrity, and availability impacts, prioritize patching of internet-facing or multi-tenant MongoDB instances first.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
