If an attacker could cause such an aggregation to occur, they could maliciously crash MongoDB in a DoS attack. This vulnerability affects MongoDB versions prior to 5.0.4, 4.4.11, 4.2.16.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2022-04-12T18:16:51.000000Z"}, {"uuid": "8a9bc66d-a3f3-4e75-95f0-b1447855b22b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-32040", "type": "seen", "source": "https://bsky.app/profile/cyfar.ca/post/3msp7qvoyw624", "content": "~Cisa~\nABB Ability Zenon's bundled MongoDB 4.2 contains 13 vulnerabilities allowing DoS, memory access, and privilege escalation.\n-\nIOCs: CVE-2025-14847, CVE-2021-32040, CVE-2021-20334\n-\n#ICS #MongoDB #ThreatIntel", "creation_timestamp": "2026-08-10T04:02:55.314460Z"}, {"uuid": "5eb250d6-ec81-47b3-8e2c-86f7c2fa2383", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2021-32040", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-26-218-01", "content": "", "creation_timestamp": "2026-08-06T16:15:25.457849Z"}]}
