CVE-2026-1830: CWE-862 Missing Authorization in davidfcarr Quick Playground
The Quick Playground plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.3.1. This is due to insufficient authorization checks on REST API endpoints that expose a sync code and allow arbitrary file uploads. This makes it possible for unauthenticated attackers to retrieve the sync code, upload PHP files with path traversal, and achieve remote code execution on the server.
AI Analysis
Technical Summary
CVE-2026-1830 is a critical remote code execution vulnerability in the Quick Playground WordPress plugin caused by insufficient authorization (CWE-862) on REST API endpoints. Attackers can exploit this by retrieving a sync code and uploading PHP files with path traversal, enabling execution of arbitrary code on the server. This affects all versions up to and including 1.3.1. The vulnerability has a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). No patch or official remediation has been published by the vendor, and the plugin is not a cloud service.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary code on the web server hosting the vulnerable Quick Playground plugin. This can lead to full compromise of the server, including data theft, service disruption, or further network penetration. The impact is rated critical based on the CVSS score and the nature of remote code execution without any required privileges or user interaction.
