[...]","Citrix has issued an urgent warning for IT administrators to patch a critical remote code execution (RCE) vulnerability, CVE-2026-107406, affecting NetScaler ADC and NetScaler Gateway appliances. The flaw, a memory overflow weakness, can lead to RCE or denial-of-service crashes when the appliances are configured as SAML IdP or SP. While Citrix is unaware of active exploitation, the company highlights a history of previously disclosed NetScaler vulnerabilities being abused by threat actors.","Citrix warns of critical NetScaler
