CISA has added CVE-2026-88771 and CVE-2026-88772, two vulnerabilities affecting Citrix NetScaler, to its Known Exploited Vulnerabilities catalog after confirming active exploitation in the wild. Both flaws are described as remote code execution vectors, meaning attackers can potentially run malicious code on affected appliances. Security teams are urged to check whether they run NetScaler and apply patches immediately, as exploited edge devices are a common entry point for intrusions.

Why now: Actively exploited remote code execution flaws in widely deployed NetScaler appliances pose an urgent risk, prompting admins to patch.
