Analysis

Impact

Insufficient data validation in the PDF handling code of Google Chrome versions prior to 150.0.7871.47 allows a remote attacker who has already gained control of the renderer process to bypass navigation restrictions using a crafted HTML page. The flaw lets the browser navigate to arbitrary URLs that were intended to be blocked, undermining the browser's navigation controls.

Affected Systems

Google Chrome desktop releases older than 150.0.7871.47 are affected. The issue exists in all earlier builds until the release that incorporates the fix, which is included in the stable channel update list referenced by Google.

Risk and Exploitability

The vulnerability is rated as Medium with a CVSS score of 6.5. The EPSS score of less than 1% indicates a low likelihood of exploitation, and it is not listed in the CISA KEV catalog. Exploitation requires a prior compromise of the renderer process; once that condition is met, the attacker can force the browser to navigate to any URL, potentially compromising user intent and session integrity.

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