> CERT-FR warns of numerous vulnerabilities in Microsoft Edge before version 151.0.4129.78 that could allow remote code execution.

CERT-FR issued an advisory covering a large batch of vulnerabilities affecting Microsoft Edge versions prior to 151.0.4129.78. The flaws could allow an attacker to achieve remote code execution as well as an unspecified security issue, though the advisory does not detail exploitation methods, attack vectors, or any evidence of active exploitation in the wild.

The advisory references over 40 individual CVEs disclosed by Microsoft on 11 August 2026, consistent with a routine monthly patch cycle rather than a targeted campaign. No indicators of compromise, threat actors, or malware are associated with this disclosure. Organizations running Microsoft Edge should apply the vendor's patches referenced in the bulletin to remediate the identified vulnerabilities.
