CVE-2026-111111
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
The Prime Slider plugin for WordPress in versions up to and including 4.7.2 is vulnerable to stored cross-site scripting (XSS) via the 'comment' parameter due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when a user visits an injected page.
Risk Assessment
An attacker could execute arbitrary JavaScript in a user's browser, potentially leading to session theft, account takeover, or other attacks. However, this requires user interaction with the injected page.
Recommendation
Update the Prime Slider plugin to a version later than 4.7.2. Additionally, consider implementing a Content Security Policy (CSP) and regularly scanning for malicious scripts.

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.

Original NVD description (English source)
The Prime Slider – Hero Slider, Carousel, WooCommerce & Post Slider Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.7.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because core wp_filter_kses leaves the submitted markup inert, but the plugin's subsequent regex fallback consumes closing quotes of allowed attribute values containing 'bdt-', promoting previously inert bytes — such as event handlers like onfocus — into real HTML attributes that are then written to the database and rendered without further sanitization.
