AI Analysis
Technical Summary
CVE-2026-13946 is a medium severity vulnerability affecting Google Chrome on iOS versions before 150.0.7871.47. It arises from an inappropriate implementation in ScriptInjections that enables a remote attacker to leak cross-origin data by leveraging a crafted HTML page. This cross-origin data leak could potentially expose sensitive information across different web origins. The vulnerability is publicly known and published but lacks detailed CVSS scoring and explicit remediation information in the provided data. The vendor advisory link is available but does not explicitly confirm patch status in the input data.
Potential Impact
The vulnerability allows remote attackers to bypass same-origin policies and leak cross-origin data, which can lead to unauthorized disclosure of sensitive information between web origins in affected versions of Chrome on iOS. This compromises user privacy and data confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html for current remediation guidance. Users should update to Chrome version 150.0.7871.47 or later once confirmed patched. Until then, exercise caution with untrusted web content on affected versions.
