Microsoft discloses ‘the mother of all’ vulnerability loads, tripling June’s previous record
Microsoft disclosed 622 vulnerabilities during July 2026 Patch Tuesday, more than triple the previous month's record of 206 and reflecting an exponential surge driven by artificial intelligence tools discovering defects at scale. Two actively exploited zero-day vulnerabilities in Active Directory Federation Services and SharePoint Server were included among the batch, with 63 rated as critical. The pace suggests Microsoft will exceed 2,000 or more Common Vulnerabilities and Exposures (CVEs) for the calendar year, far surpassing historical annual records.
Why it matters: All organizations running Microsoft products must prioritize patch assessment and deployment given the record volume; the presence of two actively exploited zero-days in widely deployed authentication and collaboration systems demands immediate attention to those specific fixes.
