Critical RCE in Apache Struts via OGNL Injection
CVE-2026-21847 · Affected: Apache Struts 2.x < 2.5.34
A critical remote code execution vulnerability was identified in Apache Struts allowing unauthenticated attackers to execute arbitrary commands via crafted OGNL expressions in HTTP request parameters. The Mind The Hack research team discovered this vulnerability during a routine engagement and coordinated disclosure with the Apache Foundation.
Impact
Full system compromise. An attacker can execute arbitrary OS commands with the privileges of the application server. No authentication required.
Remediation
Upgrade to Apache Struts 2.5.34 or later. If immediate patching is not possible, deploy WAF rules to block OGNL expression patterns in request parameters.
Authentication Bypass in FortiGate SSL VPN
CVE-2026-19332 · Affected: FortiOS 7.4.x < 7.4.5, 7.2.x < 7.2.9
An authentication bypass vulnerability in Fortinet FortiGate SSL VPN allows remote attackers to gain administrative access without valid credentials by sending specially crafted HTTP requests to the management interface.
Impact
Complete compromise of VPN gateway. Attackers gain full administrative control, enabling traffic interception, configuration changes, and lateral movement into the internal network.
Remediation
Apply FortiOS patches immediately. Restrict management interface access to trusted IP ranges. Enable MFA for all administrative sessions.
Privilege Escalation in Linux Kernel via io_uring Subsystem
CVE-2026-17421 · Affected: Linux Kernel 6.1 through 6.7.2
A use-after-free vulnerability in the Linux kernel io_uring subsystem allows local attackers to escalate privileges to root. The vulnerability exists in the request cancellation path when handling concurrent operations on shared ring buffers.
Impact
Local privilege escalation to root. Any unprivileged user with access to the system can gain complete control. Particularly dangerous in multi-tenant and containerized environments.
Remediation
Update to Linux kernel 6.7.3 or apply the backported patches for LTS kernels. As a temporary mitigation, disable io_uring via sysctl (kernel.io_uring_disabled=2).
Server-Side Request Forgery in Microsoft Exchange OWA
CVE-2026-14889 · Affected: Microsoft Exchange Server 2019 CU14, 2016 CU23
A server-side request forgery vulnerability in Microsoft Exchange Outlook Web Access (OWA) allows authenticated users to access internal network resources and cloud metadata endpoints from the Exchange server context.
Impact
Access to internal network services, cloud provider metadata endpoints (IMDS), and potential credential theft. Can be chained with other vulnerabilities for full environment compromise.
Remediation
Apply the February 2026 Microsoft security update. Restrict outbound network access from Exchange servers. Monitor for unusual outbound connections.
SQL Injection in SAP NetWeaver Application Server
CVE-2026-12556 · Affected: SAP NetWeaver AS ABAP 7.50 through 7.93
A blind SQL injection vulnerability in SAP NetWeaver Application Server ABAP allows remote attackers to extract sensitive data from the underlying database. The vulnerability exists in the user management API and is exploitable by any authenticated user.
Impact
Full database compromise. Attackers can extract credentials, business data, and configuration details. In SAP environments, this typically leads to exposure of financial records, employee data, and supply chain information.
Remediation
Apply SAP Security Note 3412789. Implement database activity monitoring. Review and restrict user permissions on affected API endpoints.
Remote Code Execution in Cisco IOS XE Web UI
CVE-2025-48912 · Affected: Cisco IOS XE 17.x with Web UI enabled
A remote code execution vulnerability in the Cisco IOS XE web management interface allows unauthenticated attackers to create privileged accounts and execute commands on the underlying operating system. The Mind The Hack threat intelligence team detected active exploitation across European infrastructure.
Impact
Complete device takeover. Attackers can implant persistent backdoors, intercept and modify network traffic, and use compromised devices as pivot points for lateral movement.
Remediation
Disable the web UI immediately if not required. Apply Cisco patches when available. Check for indicators of compromise including unauthorized user accounts and unexpected configuration changes.
