The Linear eMerge e3-Series through version 1.00-07 is vulnerable to an OS command injection vulnerability. A remote and unauthenticated attacker can execute arbitrary OS commands via the loginid parameter when invoking the forgotpassword functionality over HTTP.

Z-Wave devices based on Silicon Labs 100, 200, and 300 series chipsets do not support encryption, allowing an attacker within radio range to take control of or cause a denial of service to a vulnerable device. An attacker can also capture and replay Z-Wave traffic. Firmware upgrades cannot directly address this vulnerability as it is an issue with the Z-Wave specification for these legacy chipsets. One way to protect against this vulnerability is to use 500 or 700 series chipsets that support Security 2 (S2) encryption. As examples, the Linear WADWAZ-1 version 3.43 and WAPIRZ-1 version 3.43 (with 300 series chipsets) are vulnerable.

Z-Wave devices based on Silicon Labs 500 series chipsets using CRC-16 encapsulation, including but likely not limited to the Linear LB60Z-1 version 3.5, Dome DM501 version 4.26, and Jasco ZW4201 version 4.05, do not implement encryption or replay protection.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Linear Oy Linear linear allows DOM-Based XSS.This issue affects Linear: from n/a through <= 2.8.0.

The Linear plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'linearblockbuycommissions' shortcode in all versions up to, and including, 2.7.12 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Linear plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.8.1. This is due to missing or incorrect nonce validation on the 'linear-debug'. This makes it possible for unauthenticated attackers to reset the plugin's cache via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
