"The version of Microsoft Edge installed on the remote Windows host is prior to 136.0.3240.76. It is, therefore, affected
by multiple vulnerabilities as referenced in the May 15, 2025 advisory.

  - Chromium/Google Chrome is vulnerable to insufficient policy enforcement in Loader. A proof-of-concept for
    this vulnerability was posted to X on May 5. (CVE-2025-4664)

  - Insufficient policy enforcement in Loader in Google Chrome prior to 136.0.7103.113 allowed a remote
    attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
    (CVE-2025-4664)

  - Chromium/Google Chrome is vulnerable to an incorrect handle provided in unspecified circumstances in Mojo.
    (CVE-2025-4609)

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