Summary
The Password Protected plugin for WordPress is vulnerable to stored cross-site scripting via the bundled Freemius SDK's purchase-completion handler in all versions up to and including 2.8.4 due to insufficient input sanitization and output escaping. Once the Freemius opt-in is complete, the handler processes the 'purchased_plan' request parameter on any wp-admin request from an authenticated user without capability, nonce, or purchase validation, and stores it in a persistent site-wide administrative notice.
Risk Assessment
An authenticated attacker with subscriber-level access or above can inject arbitrary scripts that execute automatically when an administrator views a standard admin page.
Recommendation
Update the Password Protected plugin to a version later than 2.8.4 that contains the fix.

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.

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.

Original NVD description (English source)
The Password Protected plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bundled Freemius SDK's purchase-completion handler in all versions up to, and including, 2.8.4 due to insufficient input sanitization and output escaping. Once the site's Freemius opt-in is complete (the normal state after an administrator clicks "Allow & Continue"), the handler processes the 'purchased_plan' request parameter on any wp-admin request from an authenticated user without any capability, nonce, or purchase validation, and stores it in a persistent, site-wide administrative notice. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that execute automatically when an administrator views a standard admin page such as their Profile page.
