PSMDB and MongoDB MongoBleed: impact, mitigations, and patching strategy - February 24, 2026

Speakers:  Ivan Groenewold

Discover how CVE-2025-14847 (“MongoBleed”) can expose MongoDB to high-severity information disclosure—allowing an unauthenticated remote client to extract fragments of uninitialized server memory when zlib network compression is enabled on a network-reachable instance.

In this interview, we’ll break down who’s at risk, why zlib is the trigger, and the fastest mitigation: disable zlib while keeping snappy/zstd. We’ll also show how to confirm the fix (server options, logs, and PMM metrics) and how to plan upgrades to patched releases.
