## What is CVE-2026-6169?

CVE-2026-6169 is a high-severity code injection vulnerability in cservit affiliate-toolkit – Multi-Network Affiliate & Amazon Product Display, published on 27 May 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The affiliate-toolkit plugin for WordPress is vulnerable to remote code execution in all versions up to, and including, 3.8.5. This is due to the plugin using the BladeOne templating engine's runString() method which compiles user-supplied template content into PHP code and executes it via eval() without sanitization or sandboxing. This makes it possible for authenticated attackers, with Editor-level access and above, to execute arbitrary code on the server by injecting PHP into a plugin template.

Weakness: CWE-94 (Improper Control of Generation of Code)
