Cisco Secure Email Gateway CVE-2026-76461 Critical SQL Injection Flaw Exploited in the Wild for Root Access

Cisco has confirmed active exploitation of CVE-2026-76461, a CVSS 9.8 critical SQL injection vulnerability in Secure Email Gateway. The flaw resides in AsyncOS mail parsing logic and allows unauthenticated attackers to execute arbitrary commands as root simply by sending a specially crafted email. No user interaction, authentication, or workarounds exist, leaving immediate patching as the only mitigation. Affected versions include all releases up to 15.5, 16.0, and 16.5; fixed builds are 15.5.5-014, 16.0.4-302, and 16.5.0-780. Because the gateway sits at the network perimeter with high privileges, successful compromise enables long-term email interception, lateral movement, and internal phishing campaigns. Organizations should examine mail_logs for patterns such as COPY.*TO PROGRAM and cross-check network telemetry for anomalous outbound connections.

How IT Professionals Risk Leaking Confidential Data When Using ChatGPT and Other LLMs

Artificial intelligence tools such as ChatGPT, Claude and Gemini have become daily instruments for network engineers, SOC analysts and system administrators who use them to analyze logs, debug configurations and generate scripts. The convenience comes with a serious risk: employees frequently paste large volumes of internal data into these cloud services without considering what information leaves the organization. Real-world examples include SOC teams uploading multi-thousand-line logs containing internal IP addresses, employee emails and authentication tokens, as well as network engineers sending running-config files from Cisco, FortiGate and Palo Alto devices. These files reveal VLAN structures, VPN peers, SNMP community strings and LDAP server addresses, providing attackers with valuable reconnaissance material. The Malwarebytes research team documented concrete cases where the Share function in AI platforms exposed sensitive corporate information. The underlying driver is not negligence but the universal desire to complete routine tasks faster, turning an efficiency tool into a potential data-exfiltration vector for banks, government agencies and healthcare organizations.
