2020 — ESXi/vSphere source code exposed via misconfigured file share
Cataloged incident. VMware confirmed in April 2020 that limited source code related to ESXi, Workspace One, and vSphere appeared on GitHub after a misconfigured internal file share was reachable from the Internet. The vendor emphasized ongoing integrity reviews and that the exposure was engineering artifacts rather than a customer database leak. BreachHistory indexes the row under the canonical VMware company id with recordsAffected 0. Exposed categories include Limited ESXi, Workspace One, and vSphere source fragments per VMware confirmation. No attested victim count is published for this row yet.

Patterns and analysis
- Cloud and database misconfiguration — appears across multiple VMware catalog entries; prioritize controls that address this class of failure.
- Record-count hygiene — BreachHistory indexes actor-cited figures separately from company-confirmed totals; read each row's technicalWriteup before treating counts as fact.
- 2026 monitoring — New disclosures roll into this timeline as they are verified or labeled unverified per catalog policy.
