No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (VMware by Broadcom) lists Cloud Foundry bosh-vsphere-cpi-release versions before 98.0.6 as affected. No release containing a fix is confirmed on record.

Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and vCenter to impersonate vCenter REST API and capture administrator credentials via HTTP Basic auth, leading to complete virtualization infrastructure takeover.

An attacker who can intercept traffic between the BOSH Director and vCenter can establish a malicious server impersonating the vCenter REST API. When the BOSH Director makes CPI calls to perform routine cloud infrastructure operations, the attacker captures the vCenter administrator username and password transmitted via HTTP Basic authentication.

The vulnerability stems from insufficient authentication security in the communication protocol between BOSH Director and vCenter. While HTTPS may be used, the lack of proper certificate validation and pinning allows attackers to successfully impersonate vCenter endpoints. Because vCenter credentials typically grant full administrative control over the entire virtualization estate, successful credential capture yields complete takeover of every VM, datastore, and network the CPI manages.

This exposure exists on every CPI call (including routine deployment operations, not just when tags are configured) and cannot be mitigated by supplying a CA certificate alone. The attack impacts all infrastructure managed by the compromised vCenter instance, potentially affecting hundreds or thousands of VMs across multiple deployments and environments.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

(refreshed 18× in last 7d / 87× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 100 of 143 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 43 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Traffic interception vulnerability in BOSH Director vCenter CPI allows attackers positioned between BOSH Director and vCenter to impersonate vCenter REST API and capture administrator credentials via HTTP Basic auth, leading to complete virtualization infrastructure takeover. An attacker who can…
When was the CVE record for CVE-2026-41012 published?
The CVE record for CVE-2026-41012 was published on August 29, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of September 3, 2026; the record at its source may have been updated since.
Is CVE-2026-41012 actively exploited?
CVE-2026-41012 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.1% probability of exploitation in the next 30 days (below the 1st percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-41012?
CVE-2026-41012 has a CVSS base score of 7.7 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-41012?
No fix for CVE-2026-41012 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (VMware by Broadcom) lists Cloud Foundry bosh-vsphere-cpi-release versions before 98.0.6 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-41012 are linked in the Vendor Advisories panel on this page.
