The corruption impacts data integrity and can lead to service disruption or loss of critical email filtering capabilities. This issue is rooted in improper sanitization of input for administrative functions.", "risk_and_exploitability": "The CVSS score of 3.8 classifies this vulnerability as moderate, and the EPSS score of less than 1% indicates a low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a remote authenticated attacker with administrative access and the ability to submit crafted input. While the exploitation conditions are restrictive, successful exploitation would corrupt the database, potentially impacting availability and data integrity. Monitoring for authentication and input anomalies is recommended because public exploitation evidence is currently unknown."}}}}, "created": "2026-04-02T07:52:54.534915+00:00", "title": "Improper Input Sanitization in SonicWall Email Security Enables Data Corruption", "updated": "2026-04-14T16:42:17.117621+00:00", "vendors": ["sonicwall", "sonicwall$PRODUCT$email_security"]}
