AI Analysis

Impact

A use‑after‑free flaw in Chrome’s ShapeDetection component lets a remote attacker who has already compromised the renderer process escape the browser sandbox and run arbitrary code. The vulnerability, classified as CWE‑416, permits code execution beyond the expected sandboxed environment.

Affected Systems

Any installation of Google Chrome built prior to version 155.0.8059.79, regardless of operating system, is affected. This includes stable channel releases and any other channel that has not rolled the 155.0.8059.79 update.

Risk and Exploitability

The CVSS score of 8.3 signals high severity, while the EPSS score of < 1% indicates a low likelihood of exploitation in the wild, and the vulnerability is not listed in CISA’s KEV catalog. Exploitation requires an initial compromise of the renderer process, typically via malicious web content, after which a specially crafted HTML page can trigger the use‑after‑free, resulting in full host control beyond the browser sandbox.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to Chrome 155.0.8059.79 or newer via the browser’s automatic update mechanism.
  • Enforce enterprise policies that mandate updates for all Chrome channels and block legacy builds.
  • If an upgrade is delayed, mitigate risk by disabling or restricting features that exercise ShapeDetection in the affected builds, and monitor renderer processes for anomalous activity.
