According to CoinMeta, as reported by Forkast, Microsoft has a vulnerability with a severity score of 10.0 that allows authentication bypassing. This vulnerability was quietly fixed in mid-September 2026. Microsoft also disclosed 12 clusters of vulnerabilities that affected Azure and M365 environments. Among them, there is an authentication bypassing vulnerability with a severity score of 10.0 for Azure AI Foundry. This vulnerability was discovered by Ré my and Marot and falls under the category of authentication with missing critical functions; attackers can easily exploit it over the network without any user interaction. Microsoft stated that these cloud vulnerabilities have been completely mitigated on the server side, and users do not need to take any action. This incident reflects the growing "trust by default" paradigm in corporate cloud security. Vulnerabilities with the highest severity usually trigger an emergency patching cycle in local environments, but they are quietly mitigated by cloud service providers, leaving companies in a state of permanent ignorance.
