Analysis

Impact

Side‑channel information leakage in CSS in Google Chrome prior to version 150.0.7871.47 allows a remote attacker to extract cross‑origin data via a crafted HTML page. The flaw permits the attacker to read data from a different origin, thereby compromising the confidentiality of that data. The weakness is classified as CWE‑1300.

Affected Systems

All versions of Google Chrome on any operating system running a version earlier than 150.0.7871.47 are affected.

Risk and Exploitability

The CVSS base score of 6.5 indicates moderate severity, while an EPSS score of <1% suggests a very low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers can exploit it by hosting a malicious web page that the victim opens in Chrome. The CVE description does not explicitly require privileged access, and this is inferred from the lack of mention of such a requirement. The flaw is specifically a CSS side‑channel leak and does not involve command execution or denial of service.

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

OpenCVE Recommended Actions

Upgrade all instances of Google Chrome to version 150.0.7871.47 or newer.
If an immediate upgrade cannot be performed, block external stylesheets from other origins by configuring Chrome’s policy or disabling related features until a patch is available.
Apply an enterprise browser configuration to enforce a Content Security Policy limiting style‑src directives as a temporary mitigation against cross‑origin CSS leaks.
