> CERT-FR advises patching Microsoft Edge before version 153.0.4234.49 to fix 37 vulnerabilities of unspecified impact.

CERT-FR has published an advisory covering 37 vulnerabilities in Microsoft Edge affecting versions prior to 153.0.4234.49. The French national CERT's bulletin, sourced from Microsoft's own security bulletins dated 30 September 2026, does not specify the exact nature or impact of the flaws, stating only that they allow an attacker to cause an unspecified security issue. No proof-of-concept, exploitation status, or technical detail is provided in this advisory.

Defenders running Microsoft Edge should consult the referenced Microsoft Security Response Center (MSRC) update guide entries for each CVE to determine specific impact (e.g., memory corruption, spoofing, privilege escalation) and apply the vendor patch bringing Edge to version 153.0.4234.49 or later. As this is a routine browser patch bulletin with no indication of active exploitation, it should be treated as standard patch management rather than an emergency.
