Published Sep 9, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
Description
Incorrect type conversion or cast in Safebrowsing in Google Chrome on on Mac prior to 153.0.8010.36 allowed a remote attacker to bypass system access restrictions via a crafted file. (Chromium security severity: Low)

Analysis

AI-generated

Technical impact

An incorrect type conversion or cast occurs in the Safebrowsing component of Google Chrome on macOS before version 153.0.8010.36. When a remote attacker delivers a specially crafted file, the improper conversion allows the application to treat the file data in a way that bypasses defined system access restrictions. This flaw reduces the program’s ability to enforce expected constraints.

Affected Systems

Users running Google Chrome on macOS with versions earlier than 153.0.8010.36 are affected. Only the stable channel of Chrome on macOS is mentioned; no other operating systems or product channels are listed.

Risk and Exploitability

The flaw has a CVSS score of 4.3, an EPSS below 1%, and is not in the CISA KEV catalog. The vulnerability can be exploited remotely via a crafted file delivered to a user. It allows bypassing system access restrictions. Based on the description, it is inferred that such a bypass might enable an attacker to perform unauthorized system operations, though the description does not explicitly state privilege escalation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Chrome update (153.0.8010.36 or later) on all macOS installations.
  • Confirm that Chrome’s auto‑update feature is enabled to receive future patches automatically.
  • If an update cannot be applied immediately, restrict or monitor the execution of untrusted files in the same directory used for Chrome’s safebrowsing cache to reduce the risk of exploitation.
