GoKawiilCISA gives federal agencies until Saturday to patch Citrix NetScaler flaw CVE-2026-8452
CISA has added CVE-2026-8452, a memory overflow bug in Citrix NetScaler ADC and Gateway appliances, to its Known Exploited Vulnerabilities catalog, requiring federal civilian agencies to patch by August 29. Originally described by Citrix as only enabling denial-of-service, researchers at watchTowr later demonstrated it can be exploited for root-level remote code execution, and reports indicate attackers are already deploying web shells on unpatched systems.
