Attackers are chaining these flaws to gain unauthorized access, execute remote code, steal IIS machine keys, and deploy malware for persistence. A fourth CVE (CVE-2026-58644) was subsequently confirmed exploited in the wild on July 15, 2026. Microsoft has released patches for all five covered vulnerabilities. CISA recommends enabling AMSI integration, restricting internet exposure of SharePoint servers, and reviewing telemetry for anomalous activity. AMSI and Microsoft Defender Antivirus detection signatures are available for the three originally confirmed exploited flaws. No public proof-of-concept exploits exist as of publication. ## Full article daily.dev links to this article rather than hosting it.
