CVE-2024-6376: ejson shell parser in MongoDB Compass maybe bypassed

Noroxi assessment

Priority: Monitor (action score 39/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.48% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: @mongodb-js/connection-form (npm) 1.20.1.
Severity is disputed: the assigning authority (CNA) scores it 7.0, NVD 9.8.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to @mongodb-js/connection-form (npm) 1.20.1 or later.
