Analysis

Impact

The flaw arises from an incorrect implementation of the security user interface in Chrome's WebAppInstalls feature. An attacker can serve a specially crafted HTML page that presents a prompt that looks like a legitimate browser-initiated installer dialog, enabling UI spoofing. The weakness is identified as CWE-451.

Affected Systems

All installations of Google Chrome prior to version 150.0.7871.46 are affected; version 150.0.7871.46 and later contain the fix.

Risk and Exploitability

The CVSS score of 4.3 indicates a moderate severity vulnerability, and the EPSS score of less than 1% suggests a low likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Based on the description, the attack vector is inferred to be a remote attacker serving a malicious HTML page that the user opens, which then displays the spoofed installer prompt.

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