CVE-1999-1511
HighExploitation Probability (EPSS)
High risk80th percentile - higher than 80% of all known CVEs
Summary
Version 1.11 of Xtramail contains buffer overflow vulnerabilities that can be exploited by attackers to cause a denial of service and potentially execute arbitrary commands. The attack can be carried out through long PASS commands in the POP3 service, HELO commands in the SMTP service, or long usernames in the Control Service.
Risk Assessment
The organization may experience service outages and the risk of unauthorized command execution, which could lead to serious security implications.
Recommendation
It is recommended to update Xtramail to the latest version to mitigate these vulnerabilities and to monitor logs for potential attack attempts.

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.
