CVE-2026-22557

Path Traversal Vulnerability in UniFi Network Application Enables File Disclosure and Account Manipulation

Published Mar 19, 2026 CVSS 3.1 · 10 Critical EPSS 28.7% KEV · Not listed
Description
A malicious actor with access to the network could exploit a Path Traversal vulnerability found in the UniFi Network Application to access files on the underlying system that could be manipulated to access an underlying account.

Analysis

AI-generated

Technical impact

A path traversal flaw in the UniFi Network Application allows an adversary with network access to read arbitrary files on the host and potentially manipulate files to gain access to underlying account credentials.

Affected Systems

The vulnerability affects Ubiquiti Inc's UniFi Network Application. No specific version information is supplied, so all installations should be considered at risk until vendor's‑disclosed details are available.

Risk and Exploitability

The CVSS score of 10 indicates maximum severity. EPSS score of 28% indicates a moderate likelihood of exploitation, while the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector involves crafting HTTP requests to the UniFi controller over the local network to traverse directories and access files outside the intended scope, which could lead to further compromise if privileged accounts are reached.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply any vendor‑provided patch for the UniFi Network Application.
  • If no patch is available, implement input validation to prevent traversal by restricting file path parameters to the intended directories, CWE-22 best practices.
  • Restrict network access to the controller to trusted devices only, for example by applying firewall rules to block untrusted segments.
  • Monitor the Ubiquiti community advisory link for updates on patches or workarounds.
  • Implement network segmentation to isolate the UniFi controller from untrusted segments to reduce exposure.
