"The version of Microsoft Edge installed on the remote Windows host is prior to 152.0.4191.62. It is, therefore, affected
by multiple vulnerabilities as referenced in the September 3, 2026 advisory.

  - Incorrect authorization in FileSystem in Google Chrome prior to 152.0.7977.75 allowed a remote attacker
    leveraging social engineering to execute arbitrary code outside the sandbox via a crafted HTML page.
    (Chromium security severity: High) (CVE-2026-84354)

  - Improper input validation in DataTransfer in Google Chrome prior to 152.0.7977.75 allowed a remote
    attacker leveraging social engineering to bypass system access restrictions via a co-installed app.
    (Chromium security severity: High) (CVE-2026-84325)

  - Missing authorization in FileSystem in Google Chrome prior to 152.0.7977.75 allowed a remote attacker who
    had compromised the renderer process and leveraged social engineering to obtain sensitive information via
    a crafted HTML page. (Chromium security severity: Medium) (CVE-2026-84323)

  - Use after free in Proxy in Google Chrome prior to 152.0.7977.75 allowed a remote attacker to execute
    arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: High)
    (CVE-2026-84324)

  - Uninitialized resource in V8 in Google Chrome prior to 152.0.7977.75 allowed a remote attacker to execute
    arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)
    (CVE-2026-84326)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
