Analysis

Impact

Insufficient validation of untrusted input in Chrome for iOS enables a remote attacker to craft a malicious HTML page that, when rendered in the browser, leaks data from another origin. The flaw can result in a confidentiality disclosed across origins may be exposed.

Affected Systems

The vulnerability affects Google Chrome for iOS versions earlier than 150.0.7871.47. Only Chrome for iOS is impacted; the flaw does not apply to other browsers on iOS or to later Chrome releases that incorporate the input‑validation fix.

Risk and Exploitability

The flaw has a CVSS score of 6.5, indicating a medium‑to‑high severity risk, and an EPSS score of <1%, suggesting a very low—and non‑zero—likelihood of exploitation. It is not listed in the CISA KEV catalog. The likely attack vector is a remote attacker delivering a specially crafted HTML page that the user opens in Chrome for iOS; exploitation requires no privileged conditions beyond normal browsing activities.

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

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Update Google Chrome for iOS to version 150.0.7871.47 or newer to apply the input‑validation fix.
If an update is not immediately possible, avoid opening unknown or suspicious web pages that may contain malicious HTML until the update is installed and apply any subsequent security patches promptly.
Use iOS’s built‑in web filtering or a third‑party content‑filtering solution to block potentially malicious sites until the patch is applied.
