CVE-2026-64756

Published Sep 14, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed

Description

A path handling issue was addressed with improved validation. This issue is fixed in iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An app may be able to access user-sensitive data.

Analysis

Technical impact

A path handling issue, addressed via improved validation, may allow an application to access files beyond intended directories. This flaw can lead to the disclosure of user‑sensitive data. The weakness is a classic path traversal vulnerability, categorized as CWE‑22.

Affected Systems

Affecting Apple iOS and iPadOS releases prior to version 27, Apple macOS releases before Golden Gate 27, Sequoia 15.8, or Tahoe 26.7. Users of these older operating systems are potentially exposed. The defect has been corrected in the listed later releases.

Risk and Exploitability

The CVSS score is 5.5. The EPSS score is approximately 0.18%, indicating a very low probability of exploitation. The KEV status is not listed, so no documented exploitation is known. Based on the description, the likely attack vector is local or controlled use of an application that handles arbitrary file paths. The flaw could allow a privilege‑constrained attacker to read files beyond intended directories by manipulating path inputs, potentially exposing user‑sensitive data.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade to the latest iOS, iPadOS, and macOS versions that include the fix (iOS 27, iPadOS 27, macOS Golden Gate 27 or later, macOS Sequoia 15.8 or later, macOS Tahoe 26.7 or later).
Ensure applications that handle path names are sandboxed or run with least privilege and validate input paths to allow only intended directories.
If upgrading is not possible, restrict use of applications that manipulate file paths from untrusted sources and consider disabling custom path‑handling features.
