CVE-2026-16985: CWE-434 Unrestricted Upload of File with Dangerous Type in Squeeze
The Squeeze WordPress plugin before 1.7.12 does not validate the file type or extension of the per-size image data written by one of its attachment-update actions, allowing users with the upload_files capability (Author and above) to write an executable PHP file into the uploads directory and achieve remote code execution.
AI Analysis
Technical Summary
CVE-2026-16985 is a vulnerability in the Squeeze WordPress plugin prior to version 1.7.12. The flaw arises from the lack of validation on file types or extensions for per-size image data written during an attachment-update action. Users with the upload_files capability (typically Authors and above) can exploit this to upload executable PHP files into the uploads directory, potentially achieving remote code execution on the affected system.
Potential Impact
An authenticated user with upload_files capability can upload malicious executable PHP files, leading to remote code execution. This compromises the affected WordPress site, potentially allowing full control over the server environment where the plugin is installed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict upload_files capability to trusted users only and monitor for suspicious file uploads.
