Analysis

AI-generated

Technical impact

An input validation flaw in Google Chrome’s Sync component allows a remote attacker to supply specially crafted network traffic, which can lead to the disclosure of sensitive information. The flaw exists in Chrome versions prior to 152.0.7977.65 and is classified as a medium‑severity issue by Chromium developers.

Affected Systems

Based on the description, it is inferred that all desktop users running Google Chrome releases before 152.0.7977.65 with Sync enabled are affected. The issue pertains to the Sync component handling cloud‑stored data synchronization.

Risk and Exploitability

The vulnerability permits a remote attacker to send specially crafted network traffic to Chrome’s Sync component, potentially exposing sensitive data. The description does not specify whether authentication is required, so it is unclear if the attacker needs valid Chrome credentials or can target any user with Sync enabled. The CVSS score of 6.5 reflects a medium severity, the EPSS score of less than 1% indicates a low likelihood of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. Overall, the risk is moderate and primarily threatens the confidentiality of information stored in Sync.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Chrome to version 152.0.7977.65 or later on all affected systems
  • Verify that Chrome’s auto‑update feature is enabled to receive future security patches automatically
  • If an upgrade cannot be performed immediately, disable Sync until a patched version is available to limit data exposure
