CVE-2026-6271: WordPress Career Section Plugin RCE via File Upload
The National Vulnerability Database (NVD) reports a critical arbitrary file upload vulnerability, CVE-2026-6271, in the WordPress Career Section plugin. All versions up to and including 1.7 are affected. This flaw stems from a complete lack of file type validation within the CV upload handler, allowing unauthenticated attackers to upload executable files.
This vulnerability carries a CVSS score of 9.8 (Critical), indicating maximum severity. The ability for unauthenticated users to upload arbitrary executable files makes remote code execution (RCE) a straightforward outcome. An attacker can simply bypass any intended restrictions and deploy malicious scripts directly onto the server.
For defenders, this is a clear and present danger. Any WordPress site running this plugin is an open target for full system compromise. The attacker’s calculus is simple: find a site with the plugin, upload a web shell, and gain control. Patching or removing this plugin is an immediate priority.
What This Means For You
- If your organization uses the WordPress Career Section plugin, you must immediately audit your installations. Identify all instances of this plugin and either update to a patched version (if available) or disable/remove it. This is a critical RCE vector for unauthenticated attackers, meaning your servers are exposed right now.
