A path handling issue was addressed with improved validation. This issue is fixed in Safari 26.5.2, iOS 26.5.2 and iPadOS 26.5.2, macOS Tahoe 26.5.2. Processing maliciously crafted web content may disclose sensitive user information.
AnalysisAI
Path traversal (CWE-22) in Apple's WebKit-based browser engine exposes sensitive user information when processing maliciously crafted web content in Safari, iOS, iPadOS, and macOS Tahoe prior to version 26.5.2. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms that an unauthenticated remote attacker needs only to induce a user to visit a malicious page, with no authentication or elevated privileges required. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to process maliciously crafted web content using an affected Apple product - specifically Safari prior to 26.5.2 on any platform, any browser on iOS or iPadOS prior to 26.5.2 (due to mandatory WebKit usage), or Safari/WebKit on macOS Tahoe prior to 26.5.2. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.5 with AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N reflects a medium-high severity limited strictly to confidentiality - no integrity or availability impact is present. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a domain and hosts a webpage containing specially crafted path references designed to exploit the WebKit path validation flaw. When a target user visits the page in an unpatched Safari or any iOS/iPadOS browser, the malicious content triggers a path traversal that reads sensitive local files - such as browser cookies, cached credentials, or application data - and returns that content to the attacker-controlled server. … |
| Remediation | Vendor-released patch available: update to Safari 26.5.2, iOS 26.5.2, iPadOS 26.5.2, or macOS Tahoe 26.5.2 immediately via Apple's standard update channels (Settings > General > Software Update on iOS/iPadOS; System Settings > General > Software Update on macOS). … Detailed patch versions, workarounds, and compensating controls in full report. |
