Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2025-5777 | Citrix NetScaler ADC and Gateway contain an input validation vulnerability (CVE-2025-5777, CVSS 7.5) leading to memory overread when configured as VPN or AAA virtual server. KEV-listed with EPSS 69.8% and public PoC, this vulnerability enables remote unauthenticated attackers to read sensitive data from the appliance's memory, potentially exposing session tokens, credentials, and encryption keys — similar to the Heartbleed class of memory disclosure bugs. | HIGH | 7.5 | 69.8% | 177 |

| CVE-2025-6543 | Citrix NetScaler ADC and Gateway contain a memory overflow vulnerability (CVE-2025-6543, CVSS 9.8) leading to unintended control flow and denial of service when configured as VPN or AAA virtual server. KEV-listed with public PoC, this vulnerability paired with CVE-2025-5777 (memory overread) indicates a systemic weakness in NetScaler's VPN request processing that enables both data theft and remote code execution. | CRITICAL | 9.8 | 2.0% | 121 |

| CVE-2026-3055 | An insufficient input validation vulnerability exists in Citrix NetScaler ADC and NetScaler Gateway when configured as a SAML Identity Provider, allowing attackers to trigger a memory overread condition. The vulnerability affects both the NetScaler ADC and NetScaler Gateway products across multiple versions, and successful exploitation could lead to information disclosure by reading adjacent memory contents. While no CVSS score or EPSS data is currently published, the CWE-125 classification (Out-of-bounds Read) combined with the SAML IDP configuration context suggests moderate to high real-world risk for organizations relying on these devices for identity management. | CRITICAL | 9.3 | 0.0% | 117 |

| CVE-2025-5349 | Improper access control vulnerability in NetScaler ADC and NetScaler Gateway management interfaces that allows unauthenticated attackers on the adjacent network to gain high-impact unauthorized access (confidentiality, integrity, and availability compromise) without requiring user interaction. This is a critical flaw affecting widely-deployed Citrix infrastructure used by enterprises for application delivery and remote access, with high CVSS 8.8 score reflecting the severity of direct control plane compromise. | HIGH | 8.8 | 0.1% | 64 |

| CVE-2024-12284 | Authenticated privilege escalation in NetScaler Console and NetScaler Agent allows. Rated high severity (CVSS 8.8). No vendor patch available. | HIGH | 8.8 | 0.2% | 44 |
No patch
|
| CVE-2025-0320 | Local privilege escalation vulnerability in Citrix Secure Access Client for Windows that allows an authenticated, low-privileged user to escalate their privileges to SYSTEM level without user interaction. The vulnerability affects the Citrix Secure Access Client application on Windows systems and represents a critical threat to enterprise environments where this client is deployed, as successful exploitation grants complete system control. The CVSS 7.8 score and confirmed local attack vector indicate this is a material risk for any organization using this software, though exploitation requires prior local access to an affected system. | HIGH | 7.8 | 0.0% | 39 |
No patch
|
| CVE-2025-4879 | Local privilege escalation vulnerability in Citrix Workspace app for Windows that allows low-privileged users to gain SYSTEM-level privileges through an improper privilege management flaw (CWE-269). The vulnerability has a CVSS score of 7.8 (High) with low attack complexity and no user interaction required, making it a significant local threat. Status of KEV inclusion, active exploitation, and proof-of-concept availability cannot be confirmed from provided data, but the combination of high CVSS and local attack vector suggests meaningful real-world risk for organizations running Citrix Workspace on Windows endpoints. | HIGH | 7.8 | 0.0% | 39 |
No patch

| CVE-2025-6759 | Local Privilege escalation allows a low-privileged user to gain SYSTEM privileges in Windows Virtual Delivery Agent for CVAD and Citrix DaaS | HIGH | 7.8 | 0.0% | 39 |
No patch
|
| CVE-2026-4368 | Citrix NetScaler ADC and Gateway instances configured for SSL VPN, ICA Proxy, CVPN, RDP Proxy, or AAA virtual servers are vulnerable to a race condition that enables authenticated attackers to hijack other users' sessions. An attacker with valid credentials can exploit timing-dependent conditions to cause session mixup between concurrent users, potentially gaining unauthorized access to sensitive resources or impersonating other authenticated users. No patch is currently available for this high-severity vulnerability. | HIGH | 7.7 | 0.0% | 39 |
No patch
|
| CVE-2025-4365 | CVE-2025-4365 is an arbitrary file read vulnerability affecting Citrix NetScaler Console and NetScaler SDX (SVM) that allows unauthenticated remote attackers to read sensitive files from affected systems. The vulnerability has a CVSS score of 7.5 (high severity) with a network-accessible attack vector requiring no authentication or user interaction. While specific KEV and EPSS data were not provided in the intelligence sources, the combination of high CVSS, unauthenticated access, and file disclosure capability indicates this requires prompt remediation. | HIGH | 7.5 | 0.2% | 38 |
