Affects VMware Avi/NSX Advanced Load Balancer, a widely deployed enterprise load‑balancer; exploitation can expose credentials/config and enable broader compromise.
CVE-2026-47871
Authenticated directory traversal in VMware Avi Load Balancer allows arbitrary file disclosure.
Is CVE-2026-47871 being exploited?
Not confirmed. CVE-2026-47871 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.66% probability of exploitation in the next 30 days.
How severe is CVE-2026-47871?
CVE-2026-47871 is rated High with a CVSS score of 8.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-47871?
Yes. A fix has been recorded for CVE-2026-47871. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

Patch when possible
- affected32.1.1

- affected>= 22.1.1 and <= 22.1.7
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
