What to check
- Applies to
- The 10 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.
ANSSI (French CERT) published an advisory covering multiple vulnerabilities discovered in MongoDB's ecosystem, affecting the C Driver (versions 2.x prior to 2.5.2 and versions prior to 1.30.9), C++ Driver (prior to 4.5.2), libmongocrypt (prior to 1.20.4), the MongoDB extension for VS Code (prior to 1.17.1), and the PHP Driver (versions 2.1.x prior to 2.1.9, 2.2.x prior to 2.5.1, and prior to 1.21.8).
The vulnerabilities collectively enable an attacker to compromise data confidentiality, compromise data integrity, bypass security policy, cause denial of service, and conduct cross-site request forgery (CSRF) via illegitimate rebound requests. Ten CVEs (CVE-2026-84962 through CVE-2026-84971) were assigned, corresponding to MongoDB's internal tracking tickets (CDRIVER, CXX, MONGOCRYPT, PHPC, VSCODE). No indication of active exploitation is provided; this is a routine vendor-coordinated disclosure with patches available. Organizations using affected MongoDB drivers or tooling should consult the referenced MongoDB security bulletins and update to the fixed versions.

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 16,566 reports from 147 sources, 722 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.
