CISA Elevates Cisco Email Gateway SQL Injection to Critical Threat Status
CISA has added CVE-2026-76461, a critical SQL injection vulnerability in Cisco Secure Email Gateway, to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation. This vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized data access, system compromise, and lateral movement within enterprise networks. The addition to the KEV Catalog under Binding Operational Directive (BOD) 26-04 requires federal agencies to prioritize rapid remediation of this high-risk vulnerability on publicly exposed assets. This incident highlights the continued targeting of email security infrastructure by threat actors seeking initial access to enterprise environments. As organizations increasingly rely on cloud-based email security solutions, vulnerabilities in these critical gateway systems present attractive attack vectors for data exfiltration and ransomware deployment campaigns.
