Analysis

AI-generated

Technical impact

Improper input validation in the Network component of Google Chrome on Windows allows a remote attacker who tricks a user into opening a specially crafted HTML page to read sensitive data. The flaw arises because the browser processes data from an untrusted source without sufficient sanitization. This vulnerability is classified as a low‑severity information disclosure and is identified as CWE-20.

Affected Systems

The vulnerability affects users of Google Chrome versions earlier than 152.0.7977.65 running on Windows. Systems with later releases or other operating systems are not impacted.

Risk and Exploitability

The attack requires user interaction, typically delivered through a phishing or social‑engineering campaign. No public exploits are reported and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS score is < 1%, indicating a very low probability of exploitation. The CVSS score of 6.5 signifies moderate severity of the information disclosure. Installing the patched Chrome release eliminates the risk.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to Chrome 152.0.7977.65 or newer to apply the input‑validation fix.
  • Modify browser security settings to disable or limit features that allow untrusted content to send sensitive data, such as disabling automatic network requests from embedded objects.
  • Enable or enhance anti‑phishing protections in email clients and browser extensions, and train users to recognize suspicious web pages.
