CVE-2026-6064
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
A link following vulnerability in Data Shredder components in Norton Antivirus, Avast Antivirus, and AVG Internet Security prior to 26.5.10933 on Windows allows a local, low-privileged attacker to escalate privileges to SYSTEM. During a privileged shred operation, this enables arbitrary file/folder deletion leveraged to gain NT AUTHORITY\SYSTEM privileges.
Risk Assessment
This enables local privilege escalation to SYSTEM, potentially leading to full system compromise.
Recommendation
Update the antivirus software to version 26.5.10933 or later.

Etrel INCH AC charging station management web interface prior to firmware versions 7.1.2 and 8.0.1 contains a hard-coded default credentials vulnerability that allows remote attackers to gain full Administrator access by authenticating with the factory-default account. Attackers can log in over cleartext HTTP to obtain complete charger configuration, OCPP ChargePoint Identity, and CSMS WebSocket connection details, enabling unauthorized administrative control of the charging station.
- CVE-2026-95860Critical
In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.
