CVE-2026-28907: Processing maliciously crafted web content may prevent Content Security Policy from being enforced in Apple iOS and iPadOS
CVE-2026-28907 is a vulnerability in Apple iOS and iPadOS where processing maliciously crafted web content may prevent the enforcement of Content Security Policy (CSP). This issue was addressed by Apple through improved input validation and fixed in iOS 18. 7. 9, iPadOS 18. 7. 9, and related OS versions. The vulnerability could allow bypassing CSP protections, potentially weakening web content security controls. There is no CVSS score available for this vulnerability. No known exploits in the wild have been reported. The patch is available in the specified OS versions.
AI Analysis
Technical Summary
This vulnerability involves improper handling of maliciously crafted web content in Apple iOS and iPadOS, which may cause the Content Security Policy to not be enforced as intended. CSP is a security feature designed to restrict resources the browser is allowed to load, helping to mitigate cross-site scripting and other code injection attacks. Apple fixed this issue by improving input validation in iOS 18.7.9, iPadOS 18.7.9, and other related OS versions, restoring proper CSP enforcement.
Potential Impact
If unpatched, this vulnerability could allow attackers to bypass Content Security Policy protections on affected Apple devices, potentially enabling malicious web content to execute or load resources that would otherwise be blocked. This weakens the security posture of web applications relying on CSP for defense-in-depth. However, no known exploits in the wild have been reported to date.
Mitigation Recommendations
Apple has released official fixes for this vulnerability in iOS 18.7.9, iPadOS 18.7.9, iOS 26.5, iPadOS 26.5, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, and watchOS 26.5. Users and administrators should apply these updates promptly to ensure CSP enforcement is restored. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated beyond applying the official updates.
